Three point charges are placed at the cornsers of a rectangle, as shown in the figure. Determine the change in electric potential energy of the system as a fourth point charge of -2uC, is brought to point A from infinitely far away. Assume that the three point charges remain fixed in position.

A small object with a mass of 4.92 mg carries a charge of 33.4 nC and is suspended by a thread between the vertical plates of a parallel-plate capacitor. The plates are separated by 5.79 cm. If the thread makes an angle of 12.3° with the vertical, what is the potential difference in volts between the plates? Round your answer to 1 decimal place. Add your answer
