NEET 2020 Physics Electric Potential Calculation MCQ Question

Type: MCQ-numerical-Medium-Class 12

A short electric dipole has a dipole moment of 16 × 10⁻⁹ C m. The electric potential due to the dipole at a point at a distance of 0.6 m from the centre of the dipole, situated on a line making an angle of 60° with the dipole axis is: (14πε0=9×109 N m2/C2\frac{1}{4\pi\varepsilon_0} = 9 \times 10^9 \text{ N m}^2/\text{C}^2)

A

400 V

B

zero

C

50 V

D

200 V

Correct Answer

Option D

Detailed Explanation

The potential V = pcosθ4πε0r2\frac{p \cos \theta}{4\pi\varepsilon_0 r^2}. Substituting the values, V = 200 V.
