Magnetism Question 229
Question: The net magnetic moment of two identical magnets each of magnetic moment $ M _{0} $ , inclined at $ 60{}^\circ $ with each other is
Options:
A) $ M _{0} $
B) $ \sqrt{2},M _{0} $
C) $ \sqrt{3},M _{0} $
D) $ 2M _{0} $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ M _{net}=\sqrt{M _{0}^{2}+M _{0}^{2}+2M _{0}^{2},\cos ,60^{o}} $
$ =\sqrt{3M _{0}^{2}}=\sqrt{3}M _{0} $
