Question

A thin, uniform rod without mass measures 0.200 m and is attached to a hinge at point P. At one end is a positively charged sphere, and in front of it an equal but negatively charged sphere. There is a uniform magnetic field B = 0.340 T in the region. The current in the rod is I = 6.50 A. What is the value that each load must have to keep the bar in balance in the position shown in the figure?
