Problem: Three charges of magnitude |q| = 3.0 x 10-9C are placed along the circumference of a circle with radius R = 1.0m. A charge +q lies at x = -R, a charge -q at y = -R, and a charge -q at x = R. a. Determine the electric potential at the origin of the circle. b. If a negative charge with q = -1.5 x 10-9 C brought from r= ∞ and placed at the origin, what is the change in potential energy of the system of charges?

Problem Details
Three charges of magnitude |q| = 3.0 x 10-9C are placed along the circumference of a circle with radius R = 1.0m. A charge +q lies at x = -R, a charge -q at y = -R, and a charge -q at x = R.
a. Determine the electric potential at the origin of the circle.
b. If a negative charge with q = -1.5 x 10-9 C brought from r= ∞ and placed at the origin, what is the change in potential energy of the system of charges?
