NEET Physics Electric Potential MCQ Question
Type: MCQ-numerical-Medium-Class 12
What is the electric potential at a distance r from a point charge Q, assuming the potential at infinity is zero?
A
V = kQ/r
B
V = kQr
C
V = kQ/r^2
D
V = kQ/2r
Correct Answer
Option A
Detailed Explanation
The electric potential V at a distance r from a point charge Q is given by V = kQ/r, where k is the Coulomb's constant. This is derived from the work done in bringing a unit positive charge from infinity to the point at distance r.
