The figure shows two infinite parallel plates A mid B. The charge densities of the plates A and B are`sigma_1=2.5muC//m^2` and `sigma_2=0.50muC/m^2`.calculate the electric intensity in (i) the space between the plates and (ii) outside the plates .

Text Solution

Verified by Experts

The electric intensity at P is `E_R.E_R=(S_1-S_2)xx10^-6=1/(2xx8.85xx10^-2)xx(2.5-0.5)=1.13xx10^-5N//C.`
