Two small spherical balls each carrying a charge 
(10 micro-coulomb) are suspended by two insulating threads of equal lengths 1 m each, from a point fixed in the ceiling. It is found that in equilibrium threads are separated by an angle 
between them, as shown in the figure. What is the tension in the threads?
