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

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 exerted on charge Q are F_x = +0.005 N and Fy = -0.003 N.(k = 1/4πε₀ = 9.0 × 10⁹ N ∙ m²/C²,e = 1.6 × 10^-19
C)
(a)How many excess electrons are there in charge Q?
(b)What are the charges q1 and q2, including their signs?
