Solve the given question:
Question: Point charges of +12x 10^-9 C and -12x 10^-9 C are placed 10.0 cm apart.
Part A: Compute the electrical potential at:
1. A point 6.0 cm from the positive charge along the line connecting the two charges.
2. A point 4.0 cm from the positive charge along the line connecting the two charges but on the opposite side from the negative charge.
3. A point 10.0 cm from each charge; note that this point cannot lie on the line connecting the charges.
I don't just need an answer, work and explanations/walkthrough would be much appreciated! Thanks.
