Answer 1

Answer #1

According to Gauss's Theorum Electric field ' E ' of infinite plane of charge density ' $\sigma$ ' is given by

$E = \frac{\sigma}{2 \varepsilon _o}$

Charge Density, $\sigma = 7 \mu C/m^2 = 7 * 10^{-6} C/m^2$

Vacuum permittivity, $\varepsilon _o = 8.854 * 10^{-12} F/m$

Substituting, $E= \frac{7 * 10^{-6}}{2*8.854 * 10^{-12}} = 3.96 * 10^5 N/C$ Option D
