JEE Main 2020 — Electrostatics Question with Solution
From: JEE Main 2020 (Online) 8th January Morning Slot
Question
In finding the electric field using Gauss Law
the formula is applicable. In the
formula is permittivity of free space, A is the
area of Gaussian surface and qenc is charge
enclosed by the Gaussian surface. The equation
can be used in which of the following situation?

Show full solutionCorrect option: D
Correct answer
DOnly when the Gaussian surface is an
equipotential surface and is constant on
the surface.
Step-by-step explanation
By Gauss law
When and is constant then
EA =
should be constant on the surface and the surface should be equipotential.
When and is constant then
EA =
should be constant on the surface and the surface should be equipotential.
