Question

2. (a) Two small metallic spheres, each of mass 2.00 g, are suspended as pendulums by light, non-conducting strings as shown below. 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 30° with respect to the vertical. (a) If the strings are each 10.0 cm long, what is the magnitude of the charge on each sphere? Assume that the gravitational force between the two spheres can be ignored compared to the other forces acting in the problem 30 deg 2. (b) What would happen if the charges on the two spheres were not equal? Would it be possible for the two spheres to hang symmetrically at 30 degrees angle if the charges were not equal? Explain. 2. (c) How about if the masses of the two spheres were not equal? Would it be possible for the two spheres to hang symmetrically at 30 degrees angle if the masses were not equal? Explain
