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
Charge, distribution on outer surlace of sphere is uniform
Charge, distribution on inner surface of sphere is uniform
Magnitude of force on charge $q_2$ due to induced charge on inner surface of sphere is $\frac{{k{q_1}{q_2}}}{{\left( {\frac{R}{2} + l} \right)}}$
Magnitude of force on charge $q_2$ due to induced charge o n inner surface of sphere is $\frac{{k{q_1}{q_2}}}{{{{\left( l \right)}^2}}}$
