Question 6 (2 points) Listen Three charges q1, q2, and q3 are placed on the x-axis. Charge q1 = 3.5 nC is at x = -2.5 m, charge q2 = 1.5 nC is at x = 2.0 m, and charge q3 = 4.5 nC is at x = -3.0 m. What is the electric potential at the origin? Use k = 9.0x109 N-m2/C2. (1 nc = 10-9 C) A Previous Page Next Page Page 6 of 15
