Q: How much work is done in moving a charge of 2C across two points having a potential difference 10 V?
  • A. 20Pa
  • B. 20J
  • C. 20N
  • D. 20C
Correct Answer: Option B - Q = 2C, V= 10 Volts Charge work (W)= Q V = 2×10 = 20 J
B. Q = 2C, V= 10 Volts Charge work (W)= Q V = 2×10 = 20 J

Explanations:

Q = 2C, V= 10 Volts Charge work (W)= Q V = 2×10 = 20 J
