A dielectric slab is placed in uniform electric field $E$ as shown in figure. Then

A dielectric slab of dielectric constant $K$ is placed between the plates of a parallel plate capacitor carrying charge $q.$ The induced charge $q^{\text{'}}$ on the surface of slab is given by

A capacitor is charged with a di-electric slab in the space between the plates of capacitor. The battery is disconnected and the di-electric slab is pulled out of the space. Then the force of capacitor upon slab

In the given figure, potentials of points $A$ and $B$ are

Two capacitors of capacitances $1.0$ microfarad and $2.0$ microfarad are each charged by being connected across a $5.0$-volt battery. They are disconnected from the battery and then connected to each other with resistive wires so that plates of opposite charge are connected together. What will be the magnitude of the final voltage across the $2.0$-microfarad capacitor?

Initially switch $S$ was open and capacitors $C, 2C$ were having charges $Q$ and $2Q$ respectively as shown in figure. Find charge flown in the direction $1$ shown in figure after switch $S$ is closed.

Three identical charged capacitors each of capacitance $5 \mathrm{\mu F}$ are connected as shown in figure. Potential difference across capacitor $\left(3\right),$ long time after the switches ${\mathrm{K}}_1$ and ${\mathrm{K}}_2$ are closed, is

The principle of Van de Graaff generator is
