Question

A insulating cylindrical rod of diameter d and length l(l >> d) has a uniform surface charge density such that the electric field just outside the curved surface of the cylinder at point M is Eo. Find the electric field due to charge distribution at point P (r >> l).
             

Options

A.Eo
B.Eo
C.Eo
D.Eo

Solution

Eo
λ = π∈0 de0
So ep = E0
