consider a solid metal ball with radius r and charge q. what is the electric field intensity at the center, anywhere inside the ball and anywhere outside the ball?

• physics -

The charge is on the outside. Consider Gauss' Law. When inside, the contained charge is zero. When outside, it appears that the enclosed charge is q at the origin.
