Two parallel large thin metal sheets have equal surface charge densities $(\sigma = 26.4 \times 10^{-12}\,c/m^2)$ of opposite signs. The electric field between these sheets is

A

$1.5\,N/C$

B

$1.5\times 10^{-10}\,N/C$

C

$3\,N/C$

D

$3\times 10^{-10}\,N/C$

Solution

Field between two parallel sheet

$ = \frac{\sigma }{{{ \in _0}}} = \frac{{26.4 \times {{10}^{ – 12}}}}{{8.85 \times {{10}^{ – 12}}}} = 3\,N/C$
