A point charge q1 = -1.6 uC is located at the origin, and another point charge q2 = 2.4 uC is located at point P(-0.2,1.1) meters. Determine the electric potential, in kilovolts, at point Q(-2.1,-2.9) meters, due to q1 and q2
The situation is shown in the diagram below.
The distance (r_{1}) between charge q_{1} and the point Q can be given as
The distance (r_{2}) between charge q_{2} and the point Q can be computed as follows.
Use the potential formula and make the necessary substitution to determine the potential (V_{Q}) at Q.
