NOTES ASK YOUR TEACHER PRACTICE ANOTHER The radius of a solid conducting sphere is R = 13.0 cm and it has a uniformly distributed charge of 25.5 nC on its surface. The center of the sphere is at the origin of the xy coordinate system. The locations A, B, and C are at (-R/2, 0) cm, (-R, 0) cm, and (2R, 0) cm, respectively. Determine the potential difference V - V and Vg - V. Note that the diagram is not to scale. B A C (a) VA - VB (b) VB - Vc <
