TS EAMCET · Physics · Magnetic Properties of Matter
At a location, the horizontal component of the earth's magnetic field is \(0.3 \mathrm{G}\) in the magnetic meridian and the dip angle is \(60^{\circ}\). The earth's magnetic field at this location in \(G\) is
- A 0.3
- B 0.6
- C 0.9
- D 1.2
Answer & Solution
Correct Answer
(B) 0.6
Step-by-step Solution
Detailed explanation
Using, \(\beta_H=B \cos \delta\), we get \(\begin{aligned} & 0.3=B \cos 60^{\circ} \\ & 0.3=B \times \frac{1}{2} \text { or } B=0.6 \mathrm{G} \end{aligned}\)
