a charge induces charge (opp in sign)in the dielectric med acc to the eqn q(1-1/k)k (dielectric const of the med this charge pushes the other charge q so the net force becomes less doing the maths right it would be seen f=1/kq1q2/r^2

Flux :No of lines crossing a unit area.

Feild:can be determined by density of flux feild lines (closeness of feild lines)

Potential:Is a work done in bringing a unit charge from infnity to the point under consideration potential enery divided /unit charge

Charge distribution : is uniform and non uniform it depend upon the radius of curvature inversely professional

If cyclohaxe in chair cpnfprmation is non planar tjwn how can it give elimination recn e2mech because u are req either sun co planar or anti co planar

ortho effect at work man the ch3 molucule forces the cooh gp out of the plane of beneze so no resonance can take place b/w the benzaene and cooh gp thats why more acidic

5 . f:[1/2,infinity) --> [3/4,infinity), where f(x)= x²-x+1

(x-1/2)^2+3/4=y

sqrt y-3/4 +1/2=x

hence f inverse = sqrt x-3/4+1/2

4.f'(x)=-1/(1+x)^2 is always decreasing fn in its domain hence one one

f inverse is2-y/y-1

log 3/2 x>=0

3/2x>=1

x>=2/3

2^6*2^5*2^4*2^5*2^3

provided that some of the boxes can remain empty

THE VERTICAL LINES IN FISCHER PROJECTION POINT OUT FROM PLANE OF THE PAPER AND HORIZNTAL POINT IN T THE PAPER ALSO U CAN USE R AND S TECHQUIE WHCH IS PRETTY USEFUL FOR CHIRAL MOLECULES

shouldnt the ans be 12 ays since 2!*3!

ch3 group gets oxidisefd by kmno4

Ix-1I/x-1

x + cos x dra the fraph of cosx b/w the lines x+1 and x-1

x^2 +tan x is even fn

2x+sec^2 x >0

dy/dx=m

y=dy/dx*m+c

dy/dx=d^2y/dx^2 *m

d^2y/dx^2*m-dy/dx=0

rember it has 2 has 2 degree since 2 constans are present

2 ab2 gives 2ab +b2

kp= [(x/c+x)*p]^2*[(x/c+x)*p]/[(c-x/c+x)*p]^2

kp=x^4*p/(c-x)^2(c+x)

kp=p/c^3

c: intial conc of ab2

n^r this would include the case hen one child gets no prizes

( m-n)!*(m-n+1)*n!

( m-n)!*(m-n+1)*n!

i think the ans is d bcz if e chosse any value b/w (0,pi/2) we get infinete solutions

[sin x+ cos x]=3-1-[sinx]-1-[cosx]

[sqrt2 sin(x +pi/4)]=1-([sinx]+[cosx])

[sqrt 2 sin(x+pi/4)]+[sin x ]+ [cosx]=1

x=3pi/4,
