A) \[\frac{x}{2\pi }\]
B) \[\frac{x}{2\sqrt{2}\pi }\]
C) \[\frac{x}{2\sqrt{3}\pi }\]
D) \[\frac{\sqrt{3}x}{2\pi }\]
Correct Answer: C
Solution :
Pitch\[X=\frac{2\pi m\upsilon \cos {{30}^{o}}}{qB}=\frac{2\pi m\upsilon }{qB}.\frac{\sqrt{3}}{2}\](1) Radius \[r=\frac{m\upsilon \sin {{60}^{o}}}{qB}=\frac{m\upsilon }{2qB}\] (2) From Eqs. (1) and (2), we get \[r=\frac{x}{2\sqrt{3}\pi },\]which is choice [c]. Hence, the correction option is [c].You need to login to perform this action.
