Consider the force F on a charge 'q' due to a uniformly charged spherical shell of radius $\displaystyle R$ carrying charge $\displaystyle Q$ distributed uniformly over it. Which one of the following statements is true for F, if 'q' is placed at distance $\displaystyle r$ from the centre of the shell ?
Official answer
(3)
$\displaystyle F=\frac{1}{4 \pi \epsilon_0} \frac{Q q}{r^2}$ for $\displaystyle r>R$
