Determine the charge on each metal plate measuring 3.0 cm × 3.0 cm, placed 2.0 mm apart and connected to a 12 V battery. Also, find the potential difference between them.

• A. charge = 0.33 pC, potential difference = 12 V
• B. charge = 0.33 pC, potential difference = 6 V
• C. charge = 48 pC, potential difference = 12 V
• D. charge = 48 pC, potential difference = 6 V

Answer: (C)
