A) \[2\times {{10}^{5}}\text{ }m/s\]
B) \[4\times {{10}^{5}}\text{ }m/s\]
C) \[6\times {{10}^{5}}\text{ }m/s\]
D) \[6\times {{10}^{-5}}\text{ }m/s\]
Correct Answer: B
Solution :
\[F=qvB\sin \theta \] \[v=\frac{F}{qB\sin \theta }\] \[=\frac{6.5\times {{10}^{-17}}}{26\times {{10}^{-3}}\times 1.6\times {{10}^{-19}}\times 0.39}\] \[v=4\times {{10}^{5}}m/s\]You need to login to perform this action.
