Question

A parallel plate capacitor is connected to a battery and now thick uncharged metal sheet is inserted parallel to the plates of the capacitor, select the correct statement(s).

• A. The battery will supply more charge
• B. The capacitance will decrease
• C. The potential difference between the plates will increase
• D. Equal and opposite charges will appear on the two faces of the metal plate

Answer 1

Answer: (A), (D)

The correct options are
A The battery will supply more charge
D Equal and opposite charges will appear on the two faces of the metal plate

Capacitance C increase and as q = CV
Charge q will increase.
