Suppose you have two metal spheres that are exactly the same size, separated by a very large distance. Sphere A carries an excess of eight negative charges while sphere B carries an excess of two positive charges. Sphere A is momentarily connected to Sphere B using a metal wire and then the wire is removed. Draw charge diagrams of the two spheres for the two cases below before and after the connecting wire is used. 1. Before the spheres are connected using the wire .
2. After the wire has been removed .

a) phere A has 8 negative charges and sphere B has 2 positive charges

b)  each one has then 3 negative charges

Explanation:

In this case, it is asked to determine the charge of the spheres in two conditions

a) Before connecting the cable, sphere A has 8 negative charges and sphere B has 2 positive charges

b) After connecting the cable, as the spheres are metallic, the load is distributed, we have

              q = 8 -2 = 6 negative charges

these charges are distributed between the two spheres, each one has then 3 negative charges
