A) \[3.5\times {{10}^{-7}}\]sec
B) \[7.0\times {{10}^{-7}}\]sec
C) \[1.05\times {{10}^{-6}}\]sec
D) \[2.1\times {{10}^{-6}}\]sec
Correct Answer: A
Solution :
\[T=\frac{2\pi m}{qB}=\frac{2\times 3.14\times 9\times {{10}^{-31}}}{1.6\times {{10}^{-19}}\times 1\times {{10}^{-4}}}=3.5\times {{10}^{-7}}\]secYou need to login to perform this action.
