Two charges `q_(1)` and `q_(2)` are kept on `x`-axis and electric field at different points an `x`-axis is plotted against `x`. Choose correct statement about nature and magnitudes of `q_(1)` and `q_(2)`

Options

A. `q_(1)` is positive , `q_(2)` is negative, `|q_(1)|gt|q_(2)|`
B. `q_(1)` is positive , `q_(2)` is negative, `|q_(1)|lt|q_(2)|`
C. `q_(1)` is negative , `q_(2)` is positive, `|q_(1)|gt|q_(2)|`
D. `(q_(1))` is negative , `(q_(2))` ispositive, `|(q_(1))|lt|(q_(2))|`

Answer

C

Explanation

From the direction of field from graph, it is clear that `q_(1)` is negative and `q_(2)` is positive. Now since electric field is zero to the right of `q_(2),q_(2)` should be smaller in magnitude.
