Three charged particles are placed at the corners of an equilateral triangle of side L = 1.62 m.
The charges are q1 = 3.65 µC, q2 = −8.41 µC, and q3 = −6.38 µC. Calculate the magnitude and direction (counterclockwise from the positive x axis) of the net force on q1 due to the other two charges.

Question

Three charged particles are placed at the corners of an equilateral triangle of side L = 1.62 m.
The charges are q1  =  3.65 µC, q2  =  −8.41 µC, and q3  =  −6.38 µC. Calculate the magnitude and direction (counterclockwise from the positive x axis) of the net force on q1 due to the other two charges.
