Question

I just need help with the last 3, thank you!

The figure below shows two charges of negligible dimensions: q1 = +40 nC and q2 = - 30 nC. The charges are 16 cm away from each other. Let's mark a point exactly halfway between the charges as a point A; another point (B) is 12 cm from q1 and 10 cm from q2 (see the figure). A B The electric charge at point A is zero The electric charge at point B is zero The electric potential due to the charge q1 at point A is about: 4500 v V. The electric potential due to the charge q2 at point A is about: -3375 v V. The electric potential due to the charge q1 at point B is about: 3000 V. The electric potential due to the charge q2 at point B is about: -2700 V. The net electric potential at point A is about: 1125 V. The net electric potential at point B is about: 300 v V.
