Compute all parts of given problem:
Problem: The two charges in the figure below are separated by d = 1.50 cm. (Let q1 = -16.5 nC and q2 = 26.5 nC.)
Parts A: Find the electric potential at point A.
_____kV
Part B: Find the electric potential at point B, which is halfway between the charges.
_____kV
Please show the work for the calculation so I can understand what I'm doing. Thanks!
