Question

Work done in moving a charge of 25 C is 50 J. Calculate the potential difference between two points.

• A. 0.5 V
• B. 1 V
• C. 2 V
• D. 2.5 V

Hint:

Use the formula \( V = \frac{W}{Q} \) when work and charge are given to find potential difference.

Answer 1

The Correct Option is C

We use the relation between work, charge, and potential difference: \[ \text{Work done} = \text{Charge} \times \text{Potential difference} \Rightarrow W = QV \Rightarrow V = \frac{W}{Q} \] Given: \[ W = 50 \, \text{J}, \quad Q = 25 \, \text{C} \Rightarrow V = \frac{50}{25} = 2 \, \text{V} \]
