In the following diagram, the work done in moving a point charge from point P to point A , B and C are W _ A , W _ B and W _ C respectively. Then (A, B, C are points on semicircle and point charge q is at the centre of semicircle)
Options
- AW _ A = W _ B = W _ C 0
- BW _ A = W _ B = W _ C =0
- CW _ A W _ B W _ C
- DW _ A W _ B W _ C
Correct answer
A. W _ A = W _ B = W _ C 0
Step-by-step solution
As points A , B and C lie on semicircle, array ll & V_A=V_B=V_C=V & W_A=q (V_A-V_P )=q (V-V_P ) & W_B=q (V_B-V_P )=q (V-V_P ) & W_C=q (V_C-V_P )=q (V-V_P ) & W_A=W_B=W_C 0 array
