Question

What is the electric field due to a ring at a point along a tangent to it?

Answer 1

will depend on distance too..

Answer 2

The tangent and the ring are on the same plane. Only hints will suffice, I will do the rest.

Answer 3

The distance is z, I want the field at the fixed point P. The integration seems to be complicated. Any ideas how to proceed?

Answer 4

integration will surely be complicated..perhaps polar coordinates will help..

Answer 5

i'll try later...i think it can be done using a little coordinate geometry and integration..
