Question

Hello, I need some assistance with finding the Force (N) for charge A. I believe I got the other two forces correct, but I'd like to check my answer before the stupid online homework assignment starts deducting points. (What a scam) Anyway, I'd sincerely appreciate a thorough and detailed response. Thank you in advance. Have a nice day.

I will award points immediately and comment nicely to the individual that will promptly answer my question to its complete entirety as denoted in the provided uploaded image.

Three point charges have equal magnitudes, two being positive and one negative. These charges are fixed to the corners of an equilateral triangle, as the drawing shows. The magnitude of each of the charges is 7.8 mu C, and the lengths of the sides of the triangle are 2.3 cm. Calculate the magnitude of the net force that each charge experiences.

Explanation / Answer

F = k*q^2/r^2 = 1035 N

net force on A Fnet = (F^2 + F^2 + 2*F*F*cos(60) = F*sqrt(3) = 1792 N

net force on B Fnet = (F^2 + F^2 + 2*F*F*cos(120) = F = 1035 N

net force on C Fnet = (F^2 + F^2 + 2*F*F*cos(120) = F = 1035 N
