Consider the force $F$ on a charge ' $q$ ' due to a uniformly charged spherical shell of radius $R$ carrying charge $Q$ distributed uniformly over it. Which one of the following statements is true for $F$ , if ' $q$ ' is placed at distance $r$ from the centre of the shell?

Options:

Answer:

Solution:

$E = O, r < R$

$= \frac{qQ}{r^{2}}, r \geq R$

Inside $F = 0$ and outside sphare

$F = \frac{2 Qq}{4 π \in_{0} r^{2}}$
