4. (7 points) Two positive charges and one negative charge of magnitude 1 uC each are arranged as shown, far from other objects. (a) What is the magnitude of the net force on the negative charge? (b) The positive charges are fixed in place, and the negative charge is allowed to move, starting from rest in its pictured location. Carefully draw a clearly labeled vector on the diagram that could represent the direction of the initial acceleration of the negative charge. Precise calculation is not necessary. (c) Will the magnitude of the acceleration of the negative charge increase, decrease, or remain constant in the first few moments after it begins to move?
