A) \[1.6\times {{10}^{15}}\]m/s
B) \[6\times {{10}^{-6}}\]m/s
C) \[3.75\times {{10}^{3}}\]m/s
D) \[3.75\times {{10}^{2}}\]m/s
E) None of these
Correct Answer: C
Solution :
When electron moves in both electric and magnetic fields then, \[qE=qvB\] \[v=\frac{E}{B}=\frac{1500}{0.40}\] \[=3750\,\,m\text{/}s\] \[v=3.75\times {{10}^{3}}m\text{/}s\]You need to login to perform this action.
