A charge of 18.0?C is held fixed at the origin.
A) If a -6.50?C charge with a mass of 3.00g is released from rest at the position (0.925 m, 1.17 m), what is its speed when it is halfway to the origin?
B) Suppose the -6.50?C charge is released from rest at the point x = 12(0.925m) and y = 12(1.17m). When it is halfway to the origin, find the speed of the charge.
