A Small metal sphere of charge –2.0 x 104 C sits on the roof of a 5.0-kg cart as shown. The sphere moves toward another sphere of charge +1.5 x 10-3 C, located on the wall. As it moves, the cart pulls a cable that passes over a pulley and lifts an object with mass 10 kg. The cart starts at rest 5.0 m from the wall charge. (a) What is its speed when it is 2.0 m from the wall charge? (b) What assumptions did you make?
