1.	An electric charge `10^-3muC` is placed at the origin (0, 0) of X-Y co-ordinate system. Two points A and B are situated at `(sqrt2, sqrt2)` and (2, 0) respectively. The potential difference between the points A and B will beA. ` 4.5 volt `B. `9 volt`C. `zero`D. `2 volt
Answer» Correct Answer - C Since, `V_A = 9 xx 10^9 (10^(-9))/({2 +2}^(1//2) = 4.5` volt, `V_B = 9 xx 10^9 (10^(-9))/{4 + 0 }^(1//2)` volt , `V_A - V_B =0` .
