Q: How much work is done in moving a charge of 5Q across two points having a Potential difference of 10V?
  • A. 50 A
  • B. 50 C
  • C. 50 J
  • D. 50 V
Correct Answer: Option C - We know that, Work = Voltage × Charge Here, Charge (Q) = 5 Q Voltage (V) = 10 V (Electrical potential difference is also known as voltage.) W = V × Q W = 10 × 5 W = 50 J
C. We know that, Work = Voltage × Charge Here, Charge (Q) = 5 Q Voltage (V) = 10 V (Electrical potential difference is also known as voltage.) W = V × Q W = 10 × 5 W = 50 J

Explanations:
