2. Electric Potential and Capacitance
medium
A solid conducting sphere has cavity, as shown in figure. A charge $+ {q_1}$ is situated away from the centre. A charge $+q_2$ is situated outside the sphere then true statement is
A
Charge, distribution on outer surlace of sphere is uniform
B
Charge, distribution on inner surface of sphere is uniform
C
Magnitude of force on charge $q_2$ due to induced charge on inner surface of sphere is $\frac{{k{q_1}{q_2}}}{{\left( {\frac{R}{2} + l} \right)}}$
D
Magnitude of force on charge $q_2$ due to induced charge o n inner surface of sphere is $\frac{{k{q_1}{q_2}}}{{{{\left( l \right)}^2}}}$
Solution
Net force on charge $+q_2$ due to induced charge on inner surface of sphere and charge $+q_1$, is 'zero'.
