Question

5, An electron is forced to move from a positively charged plate toward a negatively charged plate by an external nonconservative force. A. Its potential energy and total energy both B. Its potential energy and total energy both C. Its potential energy increases; its total increase decrease energy stays the same. D. Its potential energy decreases; its total energy stays the same. Its potential energy increases; its total energy decreases. E. 6. In the figure, I place an extra resistor Rc in parallel with the resisters in the circuit. (The battery has no internal resistance.) The current passing through Ra (the resistor on the far left) will A. Drop B. Rise C. Stay the same D. Rise if Rc > RA but drop if Rc < RA E. Drop if Rc>RA but rise if Rc< RA

please answer these two questions and explain why

Answer 1

When an electron moves from a positively charged plate to a negatively charged plate, work has to be done on the electron. * This work done gets stored as potential energy of the system. * Thus potential energy of the electron increase. *Here the work done by non-conservative forces is positive, hence the mechanical energy of the system increase. * So, (A) potential energy and total energy both increase. \r\n * Current will stay the same because even after adding the resistor, the potential across R_A remains the same as before at Delta V/ * option (C) is correct.
