Question

a charged is distributed over a ring of radius a obtain an expression for electric field on the axis of ring hence show that for a large distance ring behave like point charge​

Answer 1

Answer:

Obtain an expression for the electric intensity E at a point on the axis of the ring. Hence, show that for points at large distance from the ring, it behaves like a point charge. At the centre (X = 0) , electric field is zero. ...
