A Point Charge Q = -12 μC, and Two Other

Question 3

Short Answer

A point charge Q = -12 μC, and two other charges q2 and q2, are placed on x-y axes as shown in the figure. The electric force components on charge Q are Fx = +0.005 N and Fy = -0.003 N. (k = 1/4πε0 = 9.0 × 109 N ∙ m2/C2, e = 1.6 × 10-19C)
(a) How many excess electrons are there in charge Q?
(b) What are the charges q1 and q2, including their signs?
