What is the electric field and potential at a distance x

Reference no: EM13997211

A sphere of radius R and total charge Q is drilled into so that it is hollowed out vertically (along the z-axis) with a cylindrical space of radius a (where a << R ). What is the electric field and potential at a distance x along the x-axis? (Hint: the charge is smaller since a piece of the sphere was drilled out.)
