Which of the following statements are true?
(A) The potential energy for a system of two negative point charges is negative
(B) Electrostatic force is a conservative force
(C) Negative potential energy between two charges implies that the force between them is repulsive
(D) Electrostatic potential energy is a scalar quantity
Choose the correct answer from the options given below:
- A (B) and (D) only
- B (A), (B) and (D) only
- C (B), (C) and (D) only
- D (A) and (D) only
Answer & Solution
Correct Answer
(A) (B) and (D) only
Step-by-step Solution
Detailed explanation
Statement (A): \( U = \frac{k q_1 q_2}{r} \). For two negative charges, \( q_1 q_2 > 0 \), so \( U > 0 \). False. Statement (B): Electrostatic force is a conservative force. True. Statement (C): Negative potential energy implies attractive force, not repulsive. False. Statement…
