NEET Physics Electric Field MCQ Question
Type: MCQ-numerical-Easy-Class 12
What is the magnitude of the electric field E at a point P located at a radial distance r from the center of a uniformly charged thin spherical shell of radius R, where r > R?
A
E = σR^2/ε₀r²
B
E = σ/2ε₀
C
E = σ/ε₀
D
E = 0
Correct Answer
Option A
Detailed Explanation
For a point outside a uniformly charged thin spherical shell, the electric field is given by E = σR^2/ε₀r², where σ is the surface charge density.
