Application +4 | -1

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

18 \times 10^{-22} \mathrm{~Cm}^{-2}

. The electric field between the plates is:

View answer and explanation

Correct option: A

2.03 \times 10^{-10} \mathrm{~NC}^{-1}

Option A (

2.03 \times 10^{-10} \mathrm{~NC}^{-1}

) is correct because the electric field between two large, thin metal plates with opposite surface charge densities is given by

\frac{\sigma}{\varepsilon_0}

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase

Statement-II: Electric field produced by charge may favour the existing electric filed Two particles having equal mass and charge
are separated by a distance
