In the following diagram, the work done in moving a point charge from point P to point \(\mathrm{A}, \mathrm{B}\) and C are \(\mathrm{W}_{\mathrm{A}}, \mathrm{W}_{\mathrm{B}}\) and \(\mathrm{W}_{\mathrm{C}}\) respectively. Then (A, B, C are points on semicircle and point charge \(q\) is at the centre of semicircle)

1. A \(\mathrm{W}_{\mathrm{A}}=\mathrm{W}_{\mathrm{B}}=\mathrm{W}_{\mathrm{C}} \neq 0\)
2. B \(\mathrm{W}_{\mathrm{A}}=\mathrm{W}_{\mathrm{B}}=\mathrm{W}_{\mathrm{C}}=0\)
3. C \(\mathrm{W}_{\mathrm{A}}\gt\mathrm{W}_{\mathrm{B}}\gt\mathrm{W}_{\mathrm{C}}\)
4. D \(\mathrm{W}_{\mathrm{A}} \lt \mathrm{W}_{\mathrm{B}} \lt \mathrm{W}_{\mathrm{C}}\)
