Two flat conductors are placed with their inner faces separated by 6.0 mm. If the surface charge density on one of the inner faces is 40 pC/m2, what is the magnitude of the electric potential differences between the two conductors?
a. 36 mV
b. 18 mV
c. 32 mV
d. 27 mV
e. 14 mV

Question 2

a. +1.8 V
b. +29 V
c. +27 V
d. +7.2 V
e. +9.0 V
