Electric PotentialHardQuestion 31457
Question
Potential at a point due to an electric dipole (p) at distance r, angle θ from dipole axis:
- Akp cosθ/r²Correct
- Bkp sinθ/r²
- Ckp/r²
- Dkp cosθ/r
Correct answer
kp cosθ/r²
Explanation
V_dipole = kp cosθ/r². At θ=0 (axial): V = kp/r². At θ=90° (equatorial): V = 0.
