Hi,
You should do a self study of 5 hours every day. This does not include the time you spend in school and tuitions. You will find that to cope up with the syllabus, 5 hours or more will be required.
For AIEEE, you need not do a separate study. Just check for anything extra in the AIEEE syllabus which you may not have covered otherwise, and can study those portions as well.
You must attempt previous year question papers of both IIT-JEE and AIEEE.

Other than that, go by a weekly time table covering all the three subjects. This will help you.

Best of luck.

Hi Rosey,
Any basic book on organic chemistry will help you prepare for AIEEE.
Read NCERT (class 11 and 12) organic portion.
You can also read the organic portion from Comprehensive Chemistry (CBSE board).
And as Gopi suggests, you can also go through Arihant for closing down on your preparation.

All the best and do well.

Hi Amrit,
I studied NCERT books myself for my JEE way back in 1996-97. The books have been written for a very good understanding of the subjects. You must read NCERT books.

Apart from that, you can read the following books:
Physics
H C Verma (Part 1 and 2)
Kumar and Mittal (Part 1 and 2)

Chemistry
Comprehensive Chemistry (CBSE board)
Organic Chemistry by Morrison Boyd
Concise Inorganic Chemistry by J D Lee (check for the latest edition)

Maths
CBSE board books
Plane Trigonometry by S L Loney
Elements of coordinate geometry by S L Loney
Algebra by Hall and Knight

Hi Kanna,

Reaction mechanisms are most important for two reasons: One that you understand the basic principle of a given reaction by knowing the electron movements and intermediates involved from reactants to products. Second, it helps you to answer organic reaction questions which you may not have read in books earlier.

(1) The book which helped me to crack IIT-JEE was Organic Chemistry by Morrison and Boyd. It deals with several reactions and their mechanisms.

(2) You should also refer to Organic Chemistry Vol 1 by I L Finar (Vol 2 if required by your syllabus).

(3) You might also want to have a look at the following book:

Elixir - Orgainc Chemistry (G. K Publications)
By Arun Kulshreshtha

Good luck with exploring Organic Chemistry.

Hi Gopi,

Appreciate the efforts you're putting in.

The book you're referring to is ok for understanding.

I would suggest you to read NCERT and comprehensive chemistry (CBSE board) books as your text books.

Moreover, you can use our study material available online as it has been written to cover all basic concepts.

You can also refer to Morrison Boyd (organic chemistry) and R C Mukerjee for brief text and numericals.

All the best.

Hi,
Gopi has amply described the practical experiment to determine the value of gravitational constant in the laboratory.

Hope this answers your query.

All the best.

Hi "narengo iit"

Can you please explain the scenario a little more.

Any object falling freely under gravity will experience a downward acceleration of g = 9.8 m/s^{2

It will also experience an upward resistive force due to air.}

Hi,
You might want to appear for such examinations to boost up your confidence and get an overall idea of some kind of rank. But more than that is your hard work that will go into preparing for IIT-JEE and taking up IIT-JEE sample papers and last years papers.
All the best.

Hi Komal,
Some of the important core topics are as follows:
Maths:
Differential Calcul
Integral Calculus
Binomial theorem
Permutation and Combination
Co-ordinate geometry: Circle, and conic sections (parabola in particular)
Complex numbers

Physics:
Newton's laws
Friction
Gravitation
Heat and laws of thermodynamics (cover it completely)
Capacitance and Inductance
Current electricity
Modern Physics (try to cover it entirely)

Chemistry:
Mole concept (mole, equivalents, etc. and their relation)
Chemical Equilibrium
Stoichiometry
Chemical kinetics
Knowledge of the periodic table
Alcohols, Ethers, Aldehydes, Ketones, Acids, Esters, Amino compounds: their basic reactions and reaction mechanism

The concept of centre of mass has been rightly described by admin.
Consider a ball thrown vertically up in the air with a spin provided to it. A point on the surface of the ball will follow a complicated path in space owing to the spin. But the centre of the ball will follow a sraight vertical path. Hence, it is easier to describe the motion of the ball in terms of its centre of mass than in terms of point particles distributed over the entire mass of the ball.

Moment of Inertia:
Linear acceleration of a body is proportional to force applied to it and described as:
F = ma, where m is the mass of the body.
Similarly, when we talk about a body in rotational motion about an axis,
its angular acceleration is proportional to the total torque on the body.

Consider a body rotating about a fixed axis:
Then, radial acceleration of a particle at distance r from the axis is
v²/r =

² r

Radial force = m

²r. ----- (1)

Tangential acceleration = dv/dt
Tangenial force = m dv/dt = mr d

/dt = mr

. ------ (2)

Torque due to (1) about the axis is zero as it intersects the axis.
Torque due to (2) is mr²

.

Summing over all particles,
Total torque = _[i]

m_ir_i²

= I

,

where I = _[i]

m_ir_i² is the moment of inertia of the body about the axis of rotation.
Moment of inertia depends upon the choice of the axis of rotation.

Hope that clears your concept of moment of inertia.

Hi,

The question doesn't seem to be correct. Please review the question and correct/complete it. The word "circle" doesn't describe the shape of the body at hand.

Hi Akanksha,

Gopi has pretty much answered your query regarding the syllabus of specific topics.

Here's a more straight forward solution for this problem:

Consider the motion of the projectile:

At the middle of the motion, the velocity has only a horizontal component. So the angle between initial velocity and current velocity vectors is 30 degrees. When the ball hits the ground, the angle between the initial velocity and final velocity vectors is 60 degrees. So the angle doesn't exceed 60 degrees during the entire projectile motion. Hence the velocity vectors will never be perpendicular.

Hi Gopi,
I'm glad that you've pulled up your socks and taken up the preparation real seriously. You have enough time from now if you start working hard.
For physics, go topic wise. i.e Mechanics (complete it fully), Heat, etc.

For maths, try and pull Calculus a little up in time because much of basic physics will involve calculus too.

Chemistry break up is fine.

You must start making and implementing a weekly timetable, breaking down topics from the overall schedule you've planned. You might find it tough to follow it initially, but in a month or so you'll be able to meet your weekly deadlines pretty well if you keep the focus. Review your schedule after every 15 days to see what's the overall pace. Do not hurry up or run unnecessarily, leaving behind unfinished concepts. Instead move at your pace which you'll know in a month or two.

Mark important things in your textbooks/notebooks for easy future reference.

All the best.
