Physics · Electrostatic Potential

हिन्दी

Consider the following properties of an electric dipole potential: (A) Potential varies inversely as \( r^2 \). (B) Potential is maximum along the axial line where \( \theta = 0^\circ \) or \( 180^\circ \). (C) Potential is zero along the equatorial line (\( \theta = 90^\circ \)). (D) Potential depends directly on the magnitude of vector \( \mathbf{r} \). Which of the above statements are correct?

  1. (A) and (D) only
  2. (A), (B) and (C) only
  3. (B), (C) and (D) only
  4. (A), (B), (C) and (D)

Correct answer · Option 2

(A), (B) and (C) only

Explanation

Statements (A), (B), and (C) are correct. Statement (D) is incorrect because potential varies inversely as \( r^2 \), not directly with \( r \).
