Here, E=(σ/ε0) =(16×10-22/8.854×10-12) =1.8×10-10 N C-1

Q. Two large, thin metal plates are parallel and close to each other. On their inner faces, the plates have surface charge densities of opposite signs and of magnitude $16 \times 1 0^{- 22} C m^{- 2}$ . The electric field between the plates is

$1.8 \times 1 0^{- 10} N C^{- 1}$

$1.9 \times 1 0^{- 10} N C^{- 1}$

$1.6 \times 1 0^{- 10} N C^{- 1}$

$1.5 \times 1 0^{- 10} N C^{- 1}$

Here, $E = \frac{σ}{ε _{0}}$
$= \frac{16 \times 1 0 ^{- 22}}{8.854 \times 1 0 ^{- 12}}$
$= 1.8 \times 1 0^{- 10} N C^{- 1}$
