A) \[2.1\times {{10}^{-5}}\,G\]
B) \[6\times {{10}^{-5}}\,T\]
C) \[2.1\times {{10}^{-5}}\,T\]
D) \[6\times {{10}^{-5}}\,G\]
Correct Answer: C
Solution :
Radius, \[r=\frac{mv}{qB}\] or \[B=\frac{mv}{qr}\] \[=\frac{9.1\times {{10}^{-31}}\times 1.3\times {{10}^{6}}}{1.6\times {{10}^{-19}}\times 0.35}\] \[=2.1\times {{10}^{-5}}T\]
