The two charges in the figure below are separated by d = 2.50 cm.

(Let q₁ = 14.0 nC and q₂ = 27.5 nC.)

Two charges and two points lie along the perimeter of an equilateral triangle with side length d (interior angle 60.0).

• Negative charge q₁ is at the bottom left vertex.
• Positive charge q₂ is at the bottom right vertex.
• Point A is at the top vertex.
• Point B is on the bottom edge, midway between q₁ and q₂.

(a) Find the electric potential at point A. _____kV (b) Find the electric potential at point B, which is halfway between the charges. _____kV
