Solve the all parts of following question given below:
Question: Two point charges Q1 = +4.30 nC and Q2 = -3.40 nC are separated by 45.0 cm.
Part A: What is the electric potential at a point midway between the charges?
V
Part B: What is the potential energy of the pair of charges?
J
Please explain each step and equations used. I need help to solve the above question and what is the significance of the algebraic sign of your answer? Positive work must be done to separate the charges. Negative work must be done to separate the charges.
