Two neutral objects are sketched below, in black and white. There are positive and negative electric charges inside these objects, and at least some of those charges can move around. Now suppose a negative charge comes close to these objects, as shown in the sketch. Shade the objects red anywhere you expect them to become more negatively charged, and shade the objects blue anywhere you expect them to become more positively charged. 0 X ? 000 Ar

In a 1911 paper, Ernest Rutherford said: In order to form some idea of the forces required to deflect an alpha particle through a large angle, consider an atom containing a point positive charge Ze at its center and surrounded by a distribution of negative electricity, – Ze uniformly distributed within a sphere of radius R. Derive an expression for the magnitude of the electric field at the center of the atom. - Express your answer using the parameters +Ze and -Ze.
