A hollow insulated conducting sphere is given a positive charge of $10 \mathrm{\mu C}$. What will be the electric field at the centre of the sphere? The radius of the sphere is $2 \mathrm{m}$.

A charge $+q$ is at a distance $\frac{L}{2}$ above a square of side $L$. Then what is the flux linked with the surface?

Four point charges $-Q,-q,2q$ and $2Q$ are placed, one at each corner of the square. The relation between $Q$ and $q$ for which the potential at the centre of the square is zero is

An electric dipole is kept in a uniform electric field with its axis inclined at some angle to the electric field. It experiences

A point charge $q$ is rotated along a circle in the electric field generated by another point charge $Q$. The work done by the electric field on the rotating charge in one complete revolution is

The equivalent capacitance of the combination of the capacitors is

Two capacitors $C_1$ and $C_2$ in a circuit are joined as shown in the figure. The potentials of points $\mathrm{A}$ and $\mathrm{B}$ are $V_1$ and $V_2$ respectively. Then the potential of point $\mathrm{D}$ will be

Two capacitor when connected in series have a capacitance of $\mathrm{3 }\mathrm{\mu F},$ and when connected in parallel have a capacitance of $16 \mathrm{\mu F}.$ Their individual capacities are
