- Two small spheres, each of mass 2.00g, are suspended by light strings 10.0 cm in length Fig. A uniform electric field is applied in the x direction. The spheres have charges equal to -5.00 * 10-8 C and +5.00 * 10-8 C. Determine the electric field that enables the spheres to be in equilibrium at an angle =10.0°.
