A charge is situated at a certain distance from an electric dipole in the end-on position experiences a force $F.$ If the distance of the charge is doubled, the force acting on the charge will be,

In a region of space, the electric field is given by $\overrightarrow{E}=8\hat{\mathrm{i}}+4\hat{\mathrm{j}}+3\hat{\mathrm{k}}.$ The electric flux through a surface area of $100$ units in $x-y$ plane is,

A charge $q$ is placed at $O$ in the cavity in a spherical uncharged conductor. Point $S$ is outside the conductor. If the charge is displaced from $O$ towards $S,$ still remaining within the cavity,

Which of the following statements is true.

Two capacitors of capacities $C$ and $2C$ are connected in parallel and then connected in series with a third capacitor of capacity $3C\mathit{.}$ The combination is charged with $V$ volt. The charge on capacitor of capacity $C$ is,

A charge $q$ is placed at the centre of the open end of a cylindrical vessel. The flux of the electric field through the surface of the vessel is,

Two conducting spheres of radii $r_1$ and $r_2\mathit{,}$ have same electric fields near their surfaces. The ratio of their electric potentials is,

A solid conducting sphere having a charge $Q$ is surrounded by an uncharged concentric conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer of hollow shell be $V.$ If the shell is now given a charge of $-3Q,$ the new potential difference between the same two surface is,
