Q: What is the potential difference between two points A and B in an electric field if the work done in moving a charge of 5μC from A to B is 10mJ?
Solution:
Potential difference V = W/Q = 10mJ / 5μC = 10 × 10^-3 J / 5 × 10^-6 C = 2V.
Steps: 5
Show Steps
Step 1: Identify the formula for potential difference (V), which is V = W/Q, where W is the work done and Q is the charge.
Step 2: Note the values given in the question: Work done (W) is 10mJ and charge (Q) is 5μC.
Step 3: Convert the units to standard SI units: 10mJ = 10 × 10^-3 J and 5μC = 5 × 10^-6 C.
Step 4: Substitute the values into the formula: V = (10 × 10^-3 J) / (5 × 10^-6 C).
Step 5: Perform the division: V = 2V.
