Question

S Consider a ring of radius R with the total charge Q spread uniformly over its perimeter. What is the potential difference between the point at the center of the ring and a point on its axis a distance 2 R from the center?

Answer 1

There the potential difference is -0. 553 keQ/R.

What is Electric potential ?

The amount of labor required to convey a unit of electric charge from a reference point to a given place in an electric field is known as the electric potential (also known as the electric field potential, potential drop, or the electrostatic potential).

Electric potential at point 0,

V1 = ke Q/R

Electric potential at x= 2R

V2= keQ/ root5. R

Therefore potential difference is

dV = V2 - V1

Putting the values we get ,

dV = -0. 553 keQ/R
