A) \[\frac{1}{\sqrt{{{B}_{1}}\,\cos \,\alpha }}\]
B) \[\frac{1}{\sqrt{{{B}_{2}}}}\]
C) \[\frac{1}{\sqrt{{{({{B}_{1\,}}\cos \,\alpha )}^{2}}+B_{2}^{2}}}\]
D) infinite
Correct Answer: C
Solution :
[c] Resultant magnetic field in the plane, \[B=\sqrt{{{({{B}_{1}}\,\cos \,\alpha )}^{2}}+B_{2}^{2}}\] Time period, \[T=2\pi \sqrt{\frac{I}{MB}}\]You need to login to perform this action.
