NEET Physics (general) MCQ Question
Type: MCQ-fact-Hard-Class 12
What is the formula for the potential due to an electric dipole at a point in space, considering the dipole moment and the angle between the dipole and the point?
A
V = (p * cos θ) / (4 * π * ε₀ * r²)
B
V = (q * r) / (4 * π * ε₀ * p)
C
V = (q * p) / (4 * π * ε₀ * r)
D
V = (p * r) / (2 * π * ε₀ * cos θ)
Correct Answer
Option A
Detailed Explanation
The potential due to a dipole is given by the formula V = (p * cos θ) / (4 * π * ε₀ * r²), where p is the dipole moment, θ is the angle, and r is the distance from the dipole. This aligns with the expression derived in the NCERT context.
