Question

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 magnitude 27 × 10-22 C m-2. The electric field vecE in region II in between the plates is (A) 4.25 × 10-8 N C-1 (B) 6.28 × 10-10 N C-1 (C) 3.05 × 10-10 N C-1 (D) 5.03 × 10-10 N C-1

The value of vecE in the region II, in between the plates =(σ/ε0) =(27×10-22/8.85×10-12) =3.05×10-10 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 magnitude $27 \times 1 0^{- 22} C m^{- 2}$ . The electric field $E$ in region $II$ in between the plates is

$4.25 \times 1 0^{- 8} N C^{- 1}$

$6.28 \times 1 0^{- 10} N C^{- 1}$

$3.05 \times 1 0^{- 10} N C^{- 1}$

$5.03 \times 1 0^{- 10} N C^{- 1}$

The value of $E$ in the region $II$ , in between the plates $= \frac{σ}{ε _{0}}$
$= \frac{27 \times 1 0 ^{- 22}}{8.85 \times 1 0 ^{- 12}}$
$= 3.05 \times 1 0^{- 10} N C^{- 1}$
