b) Suppose that the sphere q, is released when the distance between the centers of the objects is 50 cm. Find an expression to calculate the instantaneous acceleration of q,. Hint: construct Newton's law showing Fnet acting on q2 . You can ignore gravitational effects. c) Will the acceleration of the sphere be constant as the sphere moves toward q? Support your answer. d) Suppose that the person on the right side moves the charge to an infinite distance. Will he make a positive or negative work in performing this task? Calculate the work
