Physics · Electrostatic Potential
हिन्दीConsider the following statements regarding electrostatic potential: (A) Electrostatic potential at a point is equal to the work done by an external force in bringing a unit positive charge from infinity to that point without acceleration. (B) The unit of electrostatic potential is Joule per Coulomb (\( \text{J C}^{-1} \)) or Volt. (C) Electrostatic potential depends on the magnitude of the test charge \( q \) used to define it. (D) Potential at any point due to a positive charge is positive, and due to a negative charge is negative. Which of the above statements are correct?
Correct answer · Option 2
(A), (B) and (D) only
Explanation
Statement (C) is false because potential is independent of the test charge \( q \) as work done is directly proportional to \( q \). Statements (A), (B), and (D) are true.
