In the given figure, charge +Q is placed at the centre of a circle. Work done in taking another charge +g from A to B is `W_1` and from B to C is `W_2.` What is the relation between `W_1= W_2`.

The work done in taking a unit positive charge from P to A is W_A and P to B is W_B . Then .

Consider the situation of figure . The work done in taking a point charge form P to A is W_A from P to B is W_B from P to C is W_C.

A point charge +q is placed at origin O . The work done in taking another point charge -q from the point A to point B along the circular arc as shown in the figure is .

In the electric field of a point charge ( + q) , placed at the centre of a circle , a certain test charge is carried from point A to B, C,D and E Least amount of work is done along the path

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:

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:

Find the ratio of electric work done in bringing a charge q from A to B(W_(AB)) and that from B to C(W_(BC)) in a sphere of charge Q distributed uniformly throughout its volume.

Work done in forming a liquid drop of radius R is W_(1) and that of radius 3R is W_(2) . The ratio of work done is

A point charge q_(0) is moved slowly from the centre of a ring R, ( that is carrying a charge q) to a distance x from its centre along its axis. What is the work done by the external agent in this process ? Strategy : According to work energy theorem, if there is no change in kinetic energy, we have W_(ext)+ W_(E ) = 0 implies W _(ext) = - W_(E ) = - q_(0)(V_(A)-V_(B))

A gas expands from i to f along the three paths indicated. The work done along the three paths denoted by W_1, W_2 and W_3 have the relationship
