Question
Three charged particles of q1 = 70.0 nC, q2 = −70.0 nC, and q3 = 35.0 nC are placed on the y-axis, as shown in the figure. Charge q1 has the coordinates (0, 8.00 cm), q2has the coordinates (0, −8.00 cm), and q3 is located at the origin.
a)Find the electric potential energy (in J) of the configuration of the three fixed charges.
b)A fourth particle, with a mass of 1.62 ✕ 10−13 kg and a charge of q4 = 140.0 nC, is released from rest at the point (6.00 cm, 0). Find its speed (in m/s) after it has moved freely to a very large distance away.

Transcribed Image Text:The image shows a diagram with a Cartesian coordinate system, featuring the x-axis and y-axis. It includes four point charges labeled \( q_1 \), \( q_2 \), \( q_3 \), and \( q_4 \).
- **Charge \( q_1 \)** is located on the positive y-axis. It is marked with a positive sign, indicating a positive charge.
- **Charge \( q_2 \)** is located on the negative y-axis. It is marked with a negative sign, indicating a negative charge.
- **Charge \( q_3 \)** is positioned at the origin where the x-axis and y-axis intersect. It is marked with a positive sign.
- **Charge \( q_4 \)** is located on the positive x-axis, also marked with a positive sign.
Below the diagram, there is the text:
"Charge \( q_1 \) has the coordinates (0, 8.00 cm)."
No additional graphs or complex diagrams are present in the image.
