The dotted line indicate the surface such that they lie equi-distance from the charge .q.: Write the properties of the surface.

The dotted circles indicate the surface such that they lie equal distant from the charge +q:- Write any two properties of these surfaces.

The dotted circles indicate the surface such that they lie equal distant from the charge +q:- What is the name of these surfaces?

Give any two properties of equipotential surface?

Consider an infinitely long straight uniformly charged wire with linear charge density lambda To find the electric field at P (located at a distance r from the line of charge), describe an appropriate Gaussian surface.

A spherical charged conductor has sigma as the surface charge density. The electricfield on its surface is E. The radius of the sphere is doubled keeping the surface charge density unchanged. Then the electric field on the surface of the new sphere is,

Draw the electric field lines and equipotential surface for a single positive point charge.

There Is one copper sphere and a copper shell with radii 5 cm and separated by a distance of 30 cm from the centre. They are charged to a potential of 10 V on their surfaces. The solid sphere attained a charge of Q. How much is the charge gained by the shell?
