Question: Two spheres A and B have an equal mass M and are electro statically charged such that the repulsive force acting between them has magnitude

Two spheres A and B have an equal mass M and are electro statically charged such that the repulsive force acting between them has magnitude F and is directed along line AB. Determine the angle θ, the tension in cords AC and BC, and the mass M of each sphere.
Unit used:
mN 10−3 = N

Given:
F = 20 mN
g = 9.81 m/s2
θ1 = 30 deg
θ2 = 30 deg
