This expression is same as the electric field intensity due to a point charge at a distance x from the point charge q. Thus, ring behaves like a point charge if the point of observation is far away from the ring as compared to the radius of the ring.

Is this behaves like a point charge? If yes explain.

Khushi....? ??‍? 5 years, 3 months ago

The electric field of a ring of charge on the axis of the ring can be found by superposing the point charge fields of infinitesmal charge elements. ... This is a suitable element for the calculation of the electric field of a charged disc. E=kQx/(R^2+a^2)^3/2...
