Question:

A charge of 20.2 (C is held fixed at the origin.

(a) If a -5.25-(C charge with a mass of 3.20 g 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 -5.25-(C charge is released from rest at the point x = 1/2 (0.925 m) and y = ½ (1.17 m). When it is halfway to the origin, is its speed greater than, less than, or equal to the speed found in part (a)? Explain.
