Two identical point masses with mass m are hung from silk threads of length L as shown in figure. The spheres have the same charge q = 92 = q. Show that if the angle is small, the equilibrium 1 separation s between the spheres is Hint: If is small then tan (0) sin (0). L L 0!0 mass m charge 91 mass m charge 92 qL 8= 2eomg 113
