Question

A charge +q is placed at the origin O of X-Y axis as shown in figure.The work done in a taking a charge Q from A toB along the straight line AB is

Answer 1

Answer:

Zero.

Explanation:

Since we know that the points A and B are present in the equal potential hence, we know that the potential difference between A and B will be zero. So, we can formulate that the work done W=Q.ΔV= 0.

Since, we know that for every equipotential surface the potential difference across two points in the surface will be zero.
