The answer is not infinity but depends on the charge density bcoz of Gauss Law

Total Flux=q/(epsilon0)

Flux*Area=No of field lines Ans

Though being a hypothetical concept the question is not correct its a n anomaly!

Yes its really strange.

Find a line parralel to this and passing given point.Find intersection of the two lines.Find dist b/w intersection and given point.

2-If it moves a distance x towards me my image comes 2x towards me hence it approaches me at 20m/s.2-f=R---by lens formula4-f is inversely proportional to refractive index (not exactly)thus you can decide the order as Ub>Ug>Ur -U is refractive index.

1-When dipped in water relative refractive index decreases and hence focal length increases----by lens formula.

No confusions -------Obviously you require space to form a fourth bondThere is electron cloud on all sides of a triple bond and so you cant adjust another bond.Further the p-z orbitals are oriented away from both c-atoms and cannot form a bond.

acids are formed----nitrolic acids by tautomerism-NOOH

Remember that apparent depth is the depth as estimated in another medium other than the media in which observer is.It may be rarer or denser as compared to this.app depth=real depth/n

Mechanics is most important to understand for physics.At the end you end up knowing that its just Mechanics in each and every chapter.

2---CCl3 group is deactivating as well as meta directing due to -H effect.You must have seen +H(Hyperconjugation) of Hydrogen similarly for chlorine here.1---pls explain what you mean by p-0ch3 benzene and p-ocf3 benzene etc.......single substituent cannot be named ortho- meta or para......clarify the names....

N2 has lesser molecular wt while P4 has high mol wt.

XeF4------Xe has 8 e-----4 are used in 4bond pairs----rest form 2 lone pairs----6 pairs-----sp3d2-------for min repulsions 2e- lone pairs align opposite to each other axially-----F occupy eqt positions

-------shape is square planar

-----but geometry is octahedral.

-->Remember geometry and shape are two different things but well correlated---you just need not take lone pairs into account for shape of molecule.

The electrons in non conductors require huge amt of energy to free themselves from bonds(mostly covalent) and then escape the surface against attraction of cations formed.

Just compare rate of change of momentum...i.e forcelessetr on soft surf due to compression of surface...

Properties are always the better option if available....Here

I = S ln(1-cosx)

I = S ln(1+cosx)

2I=S ln(sin^2x)

I = S lnsinx

Now solve this simple....

S---->Integral sign

Ortho is the strongest due to Ortho effectthen para by obvious reasons of stable carbocationthen meta.

Well done Rjatsen

No the friction will be zero because considering a system moving with constant velocity f self adjusts to zero.In actual fact when the person walking applies force on the ground to move there is an opposing friction otherwise not.But we can approximate the condition to be zero friction and consider man just a mass moving at constant velocity.

I am getting 210 approx.Any chance I get through!

It means that the first string is greater than the second
i.e it lies earlier in the dictionary
