JEE PHYSICS MCQ: ELECTRIC FIELDS AND CHARGES

1 Easy

1 of 1

Analyzing +4 | -1

Statement-1: If equal charge is put uniformly on a surface of two identical plates one of metal and other non-metal, then electric field in front of metal plate will be more.
Statement-2: Electric field in front of non-metal sheet is

\frac{\sigma}{2 \varepsilon_0}

where

\sigma

is the surface charge density.

View answer and explanation

Correct option: D

Statement-1 is false, Statement-2 is true

Option D is correct because the electric field in front of a metal plate is

\frac{σ}{ε_0}

, while the electric field in front of a non-metal sheet is

\frac{σ}{2ε_0}

. Therefore, Statement-1 is false, and Statement-2 is true.
