NEET Physics (general) MCQ Question
Type: MCQ-numerical-Hard-Class 12
Using the binomial approximation given by the NCERT context, what is the expression for the potential V at a large distance r from a dipole with dipole moment p, when the angle θ between the dipole axis and the position vector is small?
A
V = (p cos θ) / (4πε₀r²)
B
V = (2p cos θ) / (4πε₀r²)
C
V = (p sin θ) / (4πε₀r²)
D
V = (p cos θ) / (2πε₀r²)
Correct Answer
Option A
Detailed Explanation
The NCERT context provides the formula V = (p cos θ) / (4πε₀r²) using the binomial approximation for potential due to a dipole at large distance.
