Embibe Experts Solutions for Chapter: Interaction of Charged Particles, Electric Field and Potential, Exercise 1: West Bengal Board-2018

Why are electric lines of forces not closed loop?

The electric potential at a point $\left(x,y,z\right)$is given by $\mathrm{V}=-{\mathrm{x}}^2\mathrm{y}-{\mathrm{yz}}^3+4$ Find the electric field at that point.

Show that electrical field intensity is normal to the equipotential surface.

Define electric dipole moment. An electric dipole is placed within a uniform electric field $\left(\mathrm{E}\right)$ and is rotated to an angle $\theta =180°$. Find out the work done.
