A solid conducting sphere (radius = 7.5 cm) has a charge of 0.5 nC distributed uniformly on its surface. If point A is located at the center of the sphere and point B is 25 cm from the center, the magnitude of the electric potential difference between these two points VA - VB is a) 30.0 V, b) 150.0 V, c) 108.0 V, d) 42.0 V, e) 90.0 V, f) 18.0 V. Hint: 1n=10^-9
