Charge of mc is held fixed at the origin. (a) if a mc charge with a mass of 3.20 g is released from rest at the position 10.925 m, 1.17 m2, what is its speed when it is halfway to the origin? (b) suppose the c charge is released from rest at the point x = 1 210.925 m2 and y = 1 211.17 m2. when it is halfway to the origin, is its speed greater than, less than, or equal to the speed found in part (a)? explain. (c) find the speed of the charge for the situation described in part (b).
