Question

Two charges of

q1 = 1.6 µC

and

q2 = −2.8 µC

are

d = 0.48 m

apart at two vertices of an equilateral triangle as in the figure below.

Two charges and a point are located at the vertices of an equilateral triangle with side length d.
  • Positive charge q1 is at the bottom left vertex.
  • Negative charge q2 is at the bottom right vertex.
  • Point P is at the top vertex.
(a) What is the electric potential due to the 1.6-µC charge at the third vertex, point P?
V

(b) What is the electric potential due to the
−2.8-µC
charge at P?
