Calculate the amount of work done in assembling charge together to form a uniformly charged sphere.

A charge Q is distributed over two concentric hollow spheres of radius r and R(>r) such that the surface densities of both the spheres are equal. Find the potential at their common centre.

The potential in the region of space near the point P (-2,4,6) is

V=80x

a. Find out the electric Field vector in the region

b. Find out the Electric field vector at point P

c What is the value of potential at point P

Two circular wire loops of radii .09 m (loop I) and .05 m(Loop II) are placed such that their axes coincide and their center are .12 m apart. Charge of 10

There are three charges on a straight line One Positive Charge q, Two Negative Charge -Q. Find the value of q/Q so that the entire system is in equilibrium? Will this equilibrium be stable?

A thread of length L placed along the x-axis with one end at the origin is electrified uniformly along its length with a net charge Q.Find the potential and electric field strength at a point P which is at a distance r from the origin along the axis of rod beyond the rod.

A point electric dipole having dipole moment

Calculate the potential and field due to a dipole of dipole moment 3.5 x 10

- on its axis
- on its perpendicular bisector

15 identical mercury drops are charged to a same potential of 5 Volts. Assuming the drops to be of spherical shape, find the potential of the large drop, made up of the combination of all the charged drops.
