Question
Three charged particles of q, = 30.0 nC, q, = -30.0 nC, and q = 15.0 nC are placed on the y-axis, as shown in the figure.
Charge q, has the coordinates (0, 4.00 cm), g, has the coordinates (0, -4.00 cm), and g, is located at the origin.
(a) Find the electric potential energy (in J) of the configuration of the three fixed charges.
3 37e-5
In an empty universe (or far from anything else), the charge q, can be placed at its location with no energy investment. The charge creates an electric potential at the site for q,y and when g, is brought in
from far away, the two-charge system (q, and q,) has electric potential energy. The two charges (q, and q,) each contribute to an electric potential at the site for g, and when g, is brought in from far
away, there is an increase in electric potential energy. The total electric potential energy is the sum of these two electric potential energies. J
(b) A fourth particle, with a mass of 1.95 x 10-13 kg and a charge of q, = 60.0 nC, is released from rest at the point (3.00 cm, 0). Find its speed (in m/s) after it has moved freely to a very large distance away.
