Physics · JEE | Electric Charges and Fields
हिन्दीGiven below are two statements: Statement I: The electric field due to an infinite plane sheet of charge depends on the distance \( x \) from the sheet. Statement II: For a uniformly charged thin spherical shell, the electric field outside the shell is identical to that produced by a point charge placed at its center. In the light of the above statements, choose the most appropriate answer from the options given below:
View Answer & Solution
Correct answer · Option D
Statement I is incorrect but Statement II is correct.
Explanation
Statement I is incorrect because \( E = \frac{\sigma}{2\varepsilon_0} \) is independent of \( x \). Statement II is true because the field outside a shell acts as if all charge is concentrated at the center.
