Question
Calculate the surface electrical potential of each sphere before contact was made. Assume both spheres are initially very far away from each other, and let R = 0.5 m.
Did the electric potential gradient inside the smaller sphere increase, decrease, or stay the same before compared to after contact was made? Why or why not?
Calculate final surface electrical potential of each sphere after contact is made.

There are two conduction spheres shown in the figure above, the larger sphere has a radius of R
and the smaller one's radius is one quarter as big R/4. The larger sphere is initially positively
charged to Qo = +50.0 nC and the smaller sphere is initially un-charged. The spheres are then
brought into contact and the charge allowed to redistribute itself over both spheres until static
equilibrium is reached.
