The variation of electric field between two charge `q_1` and `q_2` along the line joining the charges is plotted against distance from `q_1` (taking rightward direction of electric field as positive) as shown in the figure. Then the correct statement is A. `q_1` and `q_2` are positive and `q_1ltq_2`B. `q_1` and `q_2` are positive and `q_1gtq_2`C. `q_1` is positive and `q_2` is negative `q_1lt|q_2|`D. `q_1 and q_2` are negative and `|q_1|lt|q_2|` |

Answer» Correct Answer - A Just to the right to `q_1` electric field is `+alpha` or in positive direction (away from `q_1)` Hence `q_1` is positive. Just to the left `q_2` electric field is `-alpha` or towards left (or away from `q_2` Hence `q_2` is also positive. further E=0 near `q_1`. Hence `q_1ltq_2` |
