Embibe Experts Solutions for Chapter: Electrostatic Potential and Capacitance, Exercise 1: Exercise

A uniform electric field exists in a region and is given by $\overrightarrow{E}=E_0\hat{\mathrm{i}}+E_0\hat{\mathrm{j}}$. There are four points $A(-a, 0)$, $B(0,-a), C(a, 0)$, and $D(0, a)$ in the $xy$ plane. Which of the following is the correct relation for the electric potential?

The electric potential at a distance of $3 \mathrm{m}$ on the axis of a short dipole of dipole moment $4\times {10}^{-12} \mathrm{coulomb}-\mathrm{metre}$ is

The electric potential in volts due to an electric dipole of dipole moment $2\times {10}^{-8}$ coulomb-metre at a distance of $3 \mathrm{m}$ on a line making an angle of $60°$ with the axis of the dipole is

Which of the following is not true?

Figure shows three circular arcs, each of radius $R$ and total charge as indicated. The net electric potential at the centre of curvature is:

A pure capacitor in an AC circuit,

If the plates of a parallel plate capacitor are not equal in area, then

The plates of a parallel plate condenser are being moved away with a constant speed $v$. If the plate separation at any instant of time is $d$, then the rate of change of capacitance with time is proportional to,
