A small sphere has charge q = +9.0C and mass m = 35 g. It is hung from a vertical spring, which causes the spring to stretch by Ax = 7.0 cm from its equilibrium length. Then a downward electric field is applied to this region of space, which causes the sphere to descend through a distance of d = 2.5 cm. What is the magnitude E of this electric field? For the limit check, investigate what happens to E if the sphere barely re- sponds to the electric field being turned on (i.e., d 0).
