Question

Which of the following curves between electric field $\left(E\right)$ at a distance $\left(x\right)$ from an infinite long uniformly charged sheet is correct?
[Assume $x$ to be very small as compared to dimension of sheet]

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Electric field near infinite long uniformly charged sheet is given by,

$E=\frac{\sigma }{2{ϵ}_0}$

Charge density $\left(\sigma \right)$ is a constant for a given sheet.

$\therefore E=\text{constant}$
And it is equivalent to line $y=c$

Hence, option $\left(d\right)$ is correct.
