Question: A point charge Q = +87.1 (C is held fixed at the origin. A second point charge, with mass m = 0.0576 kg and charge

A point charge Q = +87.1 (C is held fixed at the origin. A second point charge, with mass m = 0.0576 kg and charge q = -2.87 (C, is placed at the location (0.323 m, 0).

(a) Find the electric potential energy of this system of charges.

(b) If the second charge is released from rest, what is its speed when it reaches the point (0.121 m, 0)?
