65. (a) The electric potential is the sum of the contributions of the individual spheres. Let q 1 be the charge on one, q 2 be the charge on the other, and d be their separation. The point halfway between them is the same distance d /2 (= 1.0 m) from the center of each sphere, so the potential at the halfway point is () ( ) 92 2 8 8 2 12 8.99 10 N m C 1.0 10 C 3.0 10 C 1.8 10 V. 42 1 . 0 m qq V d ε −− ×⋅ ×− × + == = × 0 π (b) The distance from the center of one sphere to the surface of the other is d – R , where R is the radius of either sphere. The potential of either one of the spheres is due to the
