1. The problem statement, all variables and given/known data Two oppositely charged identical insulating spheres, each 56.0cm in diameter and carrying a uniform charge of magnitude 165μC , are placed 1.20m apart center to center. If a voltmeter is connected between the nearest points (a and b) on their surfaces, what will it read? 2. Relevant equations V=k((q1/r1)-q2/r2) 3. The attempt at a solution At first I thought that the potential between the two would be zero because they are equal but opposite. However, that was incorrect. I have let r=0.6 and r=0.88 however, using both was still incorrect. I do not know where to go from here.
