For the situation shown in the figure below, mark out the correct statement
Potential of the conductor is $\frac{{ - q}}{{4\pi {\varepsilon _0}\left( {d + R} \right)}}$
Potential of the conductor is $\frac{q}{{4\pi {\varepsilon _0}d}}$
Potential of the conductor can’t be determined as nature of distribution of induced charges is not known
Potential at point $B$ due to induced charges is $\frac{{ - qR}}{{4\pi {\varepsilon _0}\left( {d + R} \right)d}}$
Two uniformly charged spherical conductors $A$ and $B$ of radii $5 mm$ and $10 mm$ are separated by a distance of $2 cm$. If the spheres are connected by a conducting wire, then in equilibrium condition, the ratio of the magnitudes of the electric fields at the surface of the sphere $A$ and $B$ will be .
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
Two concentric hollow conducting spheres of radius $r$ and $R$ are shown. The charge on outer shell is $Q$. What charge should be given to inner sphere so that the potential at any point $P$ outside the outer sphere is zero?
Two concentric spherical shells of radius $R_1$ and $R_2$ have $q_1$ and $q_2$ charge respectively as shown in figure. How much charge will flow through key $k$ when it is closed
Charges $Q, 2Q$ and $-Q$ are given to three concentric conducting shells $A, B$ and $C$ respectively as shown the ratio of charges on inner and outer surfaces of shell $C$ will be
