Q1. A system consists of a uniform electric field of 42.6 N/C, directed in the positive x direction, together with a particle having a positive charge of 7.87×10^-6 C. The particle is moved from the location x = 1.50 m to the location x = 3.50 m in the field, and it is stationary before and after it is moved.

The work done on the system by external force. -6.705e-4

the work done by the field on the particle. 6.705e-4

what is the change in the potential energy of the system?

Q2. What is the instantaneous power, at a time of 0.00700 seconds, dissipated by a 200 ohm resistor in a resonant AC circuit powered by a generator with a 21.0 V highest potential difference operating at 5000 rad/s?
