Question 1

A point charge of +3.00 μC and a second charge Q are initially very far apart. If it takes of work to bring them to a final configuration in which the charge is at the point x = 1.00 mm, y = 1.00 mm, and the second charge Q is at the point x = 1.00 mm, y = 3.00 mm, find the magnitude of the charge Q.
◦ 2.15 μC
◦ 4.30 μC
◦ 4.30 nC
◦ 10.74 μC

Question 2

In the figure, +4.0-μC and -4.0-μC point charges are located as shown. Now an additional +2.00-µC point charge is placed at point A. What is the electric potential energy of this system of three charges, relative to infinity? (k = 1/4πε0 = 8.99 × 109 N ∙ m2/C2)



◦ -26.4 mJ
◦ +264 mJ
◦ +26.4 mJ
◦ 0.00 J
◦ -264 mJ
