Question
SOLVED
Answer B
The diagram shows a parallel plate capacitor with plate area A and spacing d. The capacitor can be connected to a battery of potential difference V by closing the switch. Assume d << A; the positive x axis is pointing to the right. Select all correct statements from those listed below. E.g., if A and B are correct, enter AB; if none are correct, enter N.
1) If the switch is closed and d is varied, the charge on the plates does not vary.
2) The force on plate 1 due to plate 2 is F = Q/(2?0A) , where Q is the charge on plate 2.
3) The force between the plates varies as 1/d if the switch is open.
4) If the capacitor is initially uncharged and then the switch is closed, a charge Q = ?0AV/d appears on plate 1.
5) If the switch is closed, the electric field at plate 1, due to plate 2, is ?V/d
