TS EAMCET · Physics · Magnetic Properties of Matter
A short magnetic needle is pivoted in a uniform magnetic field of induction \(1 \mathrm{~T}\). Now, simultaneously another magnetic field of induction \(\sqrt{3} \mathrm{~T}\) is applied at right angles to the first field; the needle deflects through an angle \(\theta\) whose value is
- A \(30^{\circ}\)
- B \(45^{\circ}\)
- C \(90^{\circ}\)
- D \(60^{\circ}\)
Answer & Solution
Correct Answer
(D) \(60^{\circ}\)
Step-by-step Solution
Detailed explanation
In balance condition \(B_2=B_1 \tan \theta\) or \(\quad \tan \theta=\frac{\sqrt{3}}{1}=\sqrt{3}\) \(\theta=60^{\circ}\)
