Solution

The correct option is C zero along any one of the path AB, AC, AD and AE
As all points A, B,C, D,E lie on the equipotential surface so potential will be constant.
work done, $W = q d V = 0$

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

Calculate the work done by electric field when a point charge q is moved from point B to A along the curved path. Given that electric field is created by the stationary charge Q and $V_{A} = 200 V, V_{B} = 100 V, q = 0.05 C$ , length of line segment AB = 10 cm, length of curved path = 20 cm.
