Question

obtain an expression for electric field due to an electric dipole at a point equidistant from each charge..

Answer 1

Answer:

Let E1 and E2 be electric field on P due to charges +q and −q respectively.

E1=(r−a)2kq along AP.

E2=(r+a)2kq along BP.

E=k(r2−a2)22pr.

Answer 2

Answer:

Let E1 and E2 be electric field on P due to charges +q and −q respectively.

E1=(r−a)2kq along AP.

E2=(r+a)2kq along BP.

E=k(r2−a2)22pr.
