Question 259 of 311

A Point dipole p⃗=−p0x^\vec{p}=-{p}_{0}\hat{x} is kept at the origin. The potential and electric field due to this dipole on the y−axisy-axis at a distance dd are, respectively: (Taken V=0V=0 at infinity)

Show answer and solution

Answer: (D) 0,−p⃗4πϵ0d30,\dfrac{-\vec{p}}{4\pi {\epsilon }_{0}{d}^{3}}

E⃗=−p⃗4πϵ0r3=−p⃗4πϵ0d3\vec{E}=-\dfrac{\vec{p}}{4\pi {\epsilon }_{0}{r}^{3}}=-\dfrac{\vec{p}}{4\pi {\epsilon }_{0}{d}^{3}}
V=0V=0
