A) 2
B) 5
C) 0.4
D) 0.8
Correct Answer: D
Solution :
(d) 0.8 Given \[l=50\text{ }cm=0.5\text{ }m\] \[\Rightarrow v=300\,m\,{{\min }^{-1}}\] \[=\frac{300}{60}=5\,m{{s}^{-1}}\] and \[\varepsilon =2\,V\] Magnetic field, \[B=\frac{\varepsilon }{lv}=\frac{2}{0.5\times 5}=0.8\,T\]You need to login to perform this action.
