a. Kc= 8.98755 X 102 Nm2/C2 and the charge on a proton is 1.60218 X 10-19 C. Find the potential 1.08 cm from a proton.
b. What is the magnitude of the potential difference between two points that are 1.08 cm and 2.7 cm from a proton?
c. A 18 pF is connected across a 66 V source. What charge is stored on it?
