Q. Two identical small spheres of mass 2.0 g are fastened to the ends of an insulating thread of length 0.60 m. The spheres are suspended by a hook in the ceiling from the centre of the thread. The spheres are given identical electric charges and hang in static equilibrium, with an angle of 30.0° between the string halves, as shown. Calculate the magnitude of the charge on each sphere.
