The figure shows some equipotential lines distributed in space. A charged object is moved from point A to point B.
Choose the correct option:
1. | The work done in Fig. (i) is the greatest. |
2. | The work done in Fig. (ii) is the least. |
3. | The work done is the same in Fig. (i), Fig. (ii) and Fig. (iii). |
4. | The work done in Fig. (iii) is greater than Fig. (ii) but equal to that in Fig. (i). |
