NEET Physics (general) Assertion Reason Question

Type: Assertion Reason-assertion-Easy-Class 12

Assertion (A): The potential due to an electric dipole at a point on its perpendicular bisector is zero. | Reason (R): The potential at any point due to an electric dipole is given by V = pcos⁡θ4πε0r2\frac{p \cos \theta}{4 \pi \varepsilon_0 r^2}.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option A

Detailed Explanation

The potential due to a dipole is zero on the perpendicular bisector as θ=90∘\theta = 90^\circ, making cos⁡θ=0\cos \theta = 0. Hence, R explains A.
