Figure shows the potential due to similarly charged infinite sheets with charge per unit are sigma_2 and sigma_1. From examining third plot we can deduce that

Answer»

`sigma_2gtsigma_1`
`sigma_2 ltsigma_1`
`sigma_2=sigma_1`
none of these

Solution :Negative of SLOPE of potential VERSUS `X` CURVE gives electric field. In this case, slope is negative, therefore electric field is positive. Thus field DUE to `sigma_(2)` is greater, i.e., `sigma_(2)=sigma_(1)`.
