A) 9.5
B) 7.2
C) 5.0
D) 3.2
Correct Answer: D
Solution :
[d]: Given : \[\upsilon =24\times {{10}^{6}}Hz,R=0.60\text{ }m\] We know that, \[R=\frac{mv}{qB}\] \[\therefore \]\[B=\frac{mv}{qR}\] ...(i) where \[v=\omega R=2\pi \upsilon R\] \[B=\frac{(3.34\times {{10}^{-27}})(9.04\times {{10}^{7}})}{1.6\times {{10}^{-19}}\times 0.60}=3.2T\]You need to login to perform this action.
