Electric filed lines || equi- potential surface

In a uniform electric field , equipotential surface must (i) be plane surfaces (ii) be normal to the direction to the filed (iii) be spaced such that surfaces having equal difference in potential are separated by equal distances (iv) have decreasing potentials in the direction of field

An electron goes from one equi-potential surface another along one of the four paths shown in diagram. Rank the paths according to the work by the electrostatic force from the least to greatest.

The angle between the electric lines of force and an equipotential surface is

Field potential relation | Equipotential surface | Electric Potential Energy | Self energy of spherical shell

A point charge +Q is placed in the vicinity of a conducting surface. Draw the electric field lines between the surface and the charge.
