JEE Main 2020 — Electrostatics Question with Solution
From: JEE Main 2020 (Online) 6th September Evening Slot
Question
Consider the force F on a charge 'q' due to a uniformly charged spherical shell of radius R carrying
charge Q distributed uniformly over it. Which one of the following statements is true for F, if 'q' is
placed at distance r from the centre of the shell?
Choose an option
Show full solutionCorrect option: B
Correct answer
B for r > R
Step-by-step explanation
Inside the shell for r < R
E = 0
hence F = 0
Outside the shell
E =
hence F = for r > R
