Question

4. A long straight wire sits in a plane next to a rectangular conducting loop. The loop is connected to a parallel-plate capacitor, as shown in the figure. An electron is initially at rest between the plates. Which of the following will cause the electron to accelerate toward the right plate? A. Turn a current on in the straight wire directed left to right. B. Turn a current on in the straight wire directed right to left. C. Do nothing, since the electron will always move to the right. D. There is nothing you can do to move the electron to the right.

Explanation / Answer

Option (B) is correct

If the current on in the striaght wire directed right to left then due to induced emf in rectangular loop left plate of capacitor get negative potential and right plate get positive potential. So negative charge electron is elctron is attracted by right plate (positive plate)
