What is the amount of work done in moving a point charge around a circular are of radius r at the centre where another point charge is located ?

The work done in carrying a charge q once round a circle of radius r with a charge Q at the centre is

What is the amount of work done in moving a charge of 15 between two points kept at a potentia difference of 1.2 V?

The amount of work done in moving a charge of 5 C across two points having a potential difference of 15 Volts is equal to

Find the electric flux due to a point charge 'Q' through the circular region of radius R if the charge is placed on the axis of ring at a distance x.

A charge is distributed with a linear density lamda over a rod of the length L placed along radius vector drawn from the point where a point charge q is located. The distance between q and the nearest point on linear charge is R. The electrical force experienced by the linear charge due to q is

The work done in carrying a point charge form one point to another in an electrostatic field depends on the path along which the point charge is carried.

When an electron moves in a circular path around a stationary nucleus charge at the center

In figure below a charge Q is fixed. Another charge q is moved along a circular arc MN of radius r around it, from the point M to the point N such that the length of the arc MN = 1. The work done in this process is :

The are AB with the centre C and infinitely long wire having linear charge density lambda are lying in the same plane. The minium amount of work to be done to move a point charge q_(0) from point A to B through a circular path AB of radius a is equal to

As per this diagram a point charge +q is placed at the origin O . Work done in taking another point charge -Q from the point A(0, a) to another point B(a, 0) along the staight path AB is:
