Question

find the electrical field at a distance s above one end of a line charge of length l​

Answer 1

Answer:

The general answer is most conveniently expressed in terms of the linear charge density λ; for a finite rod of length L and total charge Q

Answer 2

$e = \frac{2pks}{( {s}^{2}) - \frac{ {l}^{2} }{4} {)}^{2} } | general \: eqn.$

$e = \frac{2pk}{ {s}^{3} } | for \: short \: dipole \\ that \: is.... \\ s > > > \frac{l}{2}$
