Question

An equilateral triangle has a point charge +1.30q at each of the three vertices (A, B, C). Another point charge Q is placed at D, the midpoint of the side BC. Solve for Q if the total electric force on the charge at A due to the charges at B, C, and D is zero. where qA = qB = qC = +1.30q.

Step 1

Given: - Value of F.U (upward force) = KQQA / (sqrt(3)/2 * a)^2 - Value of F.U = 2 * F1 * cos(30°) - Value of F.D (downward force) = -F.U Show more…
