Newton's law, net force = mass X acceleration
During equilibrium, net force = 0.
During equilibrium, electrostatic force, weight and tension act on the sphere.

Problem 4 Two identical small spheres with mass, m, are hung from a very thin string of length L, as shown in figure (17.56). The radius of the spheres is small and we can treat the spheres as point like objects. The charge on each sphere is q. Determine the angle, θ, each string makes with the vertical direction. Assume that the angle is small, (Hint: when θ is small you can use that θ sin θ tan θ) mass...
Two small metallic spheres, each of mass m = 0.45 g, are suspended as pendulums by light strings from a common point. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of θ = 3.3° with the vertical. If each string has length L = 36.0 cm, what is the magnitude of the charge on each sphere?
