(A) \(Q_1\) is in stable equilibrium
(B) \(Q_2\) is in unstable equilibrium
(C) \(Q_1\) is in unstable equilibrium
(D) \(Q_2\) is in stable equilibrium
Choose the correct answer from the options given below:
- A (A) and (B) only
- B (A) and (D) only
- C (B) and (C) only
- D (C) and (D) only
Answer & Solution
Correct Answer
(B) (A) and (D) only
Step-by-step Solution
Detailed explanation
\(Q_1\): Magnetic moment \(\vec{m}\) is parallel to external magnetic field \(\vec{B}\) from \(P\) \(\implies\) stable equilibrium. \(Q_2\): Magnetic moment \(\vec{m}\) is parallel to external magnetic field \(\vec{B}\) from \(P\) \(\implies\) stable equilibrium. Correct…
