Question No.23- Two identical pith balls are charged by rubbing against each other. They are suspended from a horizontal rod through two strings of length 20 cm each, the separation
between the suspension points being 5 cm. In equilibrium, the separation between the balls is 3 cm.
Find the mass of each ball and the tension in the strings. The charge on each ball has a magnitude 2⋅0 × 10 − 8 C.
