A few electric field lines for a system of two charges `Q_1` and `Q_2` fixed at two different points on the x-axis are shown in the figure. These lines suggest that A. ` |Q_1| gt |Q_2|`B. ` |Q_1| gt |Q_2|`C. at a finite distance to the left of ` Q_1` the electric field is zerpD. at a finite distance to the left of ` Q_1` the electric field is zerp |

Answer» Correct Answer - A::D The number of field lines is proprtional to the magnitude of the charge. Hence `| Q_1 | gt | !_2 |` .Field lines emerge from a positive charge and terminate on a negative charge . Hece `Q_1` is positve and `Q_2` is negative . Therefore , at any distance to the left of `Q_1` the electric field due to `Q_1` will be higher in magitude than that due to `Q_2` and cannot cancel each other. So the correct choices are `A` and `D` . |
