Two 2.70-g spheres are suspended by 22.5-cm-long light strings (see the figure). A uniform electric field is applied in the x-direction. If the spheres have charges of −3.00 ✕ 10−8 C and +3.00 ✕ 10−8 C, determine the electric field intensity that enables the spheres to be in equilibrium at θ = 13.0°.
