MCQ
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
    $1.5\times 10^{-10}\,N/C$
  • ✓
    $3\,N/C$
  • D
    $3\times 10^{-10}\,N/C$
✓

Answer

Correct option: C.
$3\,N/C$
c
Field between two parallel sheet

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