Two parallel plane sheet `1` and `2` carry uniform charge densities `sigma_(1)` and `sigma_(2)` as shown in fig.electric field in the region marked II is `(sigma_(1) gt sigma_(2))`

Options

A. `-((sigma_(1)+sigma_(2)))/(2epsilon_(0))`
B. `-((sigma_(1)sigma_(2)))/(2epsilon_(0))`
C. `((sigma_(1)+sigma_(2)))/(2epsilon_(0))`
D. `((sigma_(1)-sigma_(2)))/(2epsilon_(0))`

Answer

4

Explanation

`E_("net")=E_(1)-E_(2)=(sigma_(1))/(2epsilon_(0))-(sigma_(2))/(2epsilon_(0)),E_("net")=(sigma_(1)-sigma_(2))/(2epsilon_(0))`
