It requires 4 J of work to move a charge of 20 C from point A to point...
Potential difference between two points is given by
Va - Vb = W/q0
Work, W = 2 J
Charge, q0 = 20 C
Potential difference = 2/20 = 0.1 V
The correct option is C.

It requires 4 J of work to move a charge of 20 C from point A to point...

- **Given Values:**
- Work done (W) = 4 J
- Charge (Q) = 20 C
- Distance (d) = 0.2 cm

- **Calculating Potential Difference (V):**
- The work done in moving a charge through a potential difference is given by the formula: W = Q * V
- Rearranging the formula to find potential difference: V = W / Q
- Substituting the given values: V = 4 J / 20 C = 0.2 J/C = 0.2 V

- **Conclusion:**
- The potential difference between point A and point B is 0.2 volts.

Therefore, the correct answer is option 'A' (0.2). This calculation demonstrates that the potential difference between the two points can be determined using the work done and the charge moved.
