A straight wire of length 30 cm has 15muC charge. Calculate the electric field intensity at a distance of 20 cm from the wire.

Why is electric field intensity inside a charged conductor zero ?

A straight rod of length l placed in vacuum is charged uniformly with an amount q of charge. Calculate the electric field intensity in SI at a point on the axis of the rod at a distance x from its nearer end. Write the result in CGS system also.
