Question

An equilateral triangle has a point charge +3.90q 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 = +3.90q.

Step 1

Since the triangle is equilateral, the magnitudes of these forces will be equal due to the symmetry and equal charges at B and C. Let's denote the side length of the equilateral triangle as \( a \). The electric force between two point charges is given by Show more…
