in gauss theorem the flux is due to the charge inside the enclosing body.
here it is ZERO.

i think u must mention the co eff. of restitution.

i have an easy ans.
the bottommost pt. should be at rest ,  hence, the force is 0 there.
F * 2R = Ia/r
& I = 1/2MR^2 + MR^2 = 3/2MR^2.
=>  a = 4f/3m

vel. of light in any med. = vel. in vacuum/refractive index of medium.
when light ray comes back then the index is same again.

pot. inside a shell remains constant.
upto R1 the only charge is q1 &pot.is KQI/R1 but the pot. due to q2, at r2 , will be KQ2/R2.
HOPE U UNDERSTOOD.

Pot. diff. will be independent of the outer charge qb.
Va =KQ1/R1 +KQ2/R2
Vb=K(Q1+Q2)/R2
Va - Vb = KQ1 (1/R1 -1/R2)

select 5 nos.from the given nos. 0,1,2,3,4,5 & then apply the above two cases.

Make 2 cases:
1) take 1,2,3,4,5
it gives 120 ways.
 
2)take 0,1,2,4,5
4 * 24 = 96
 
total- 216

ans is 120 +96 =216

NH4Cl is correct but in the aieee exam it was given that N2 is correct at fiitjee site.

I got hyperbola but ellipse is also correct b'cos we have to use mode of the distance therefore both the ans are correct.ihope all of u got it.

always apply normality eqn to such problems
no. of millimoles of Mn2+ = (NV)KMnO4
                                     =(.102)(3)(21.5)
&AMT. CAN BE FOUND by multiplying with m.wt.
