NEET Physics Electric Field MCQ Question
Type: MCQ-fact-Easy-Class 12
What is the expression for the electric field E at a point P due to a point charge q at a distance r from the charge?
A
E = (1/(4πε₀)) * (q/r²) * r̂
B
E = (4πε₀) * (q/r²) * r̂
C
E = (1/(4πε₀)) * (q/r) * r̂
D
E = (1/(4πε₀)) * (q/r³) * r̂
Correct Answer
Option A
Detailed Explanation
The electric field E at a point P due to a point charge q is given by E = (1/(4πε₀)) * (q/r²) * r̂, where r̂ is a unit vector in the direction from the charge to point P.
