A) \[{{\tan }^{-\,1}}(5.0)\]
B) \[{{\tan }^{-\,1}}(0.5)\]
C) \[{{\tan }^{-\,1}}(0.2)\]
D) \[{{\tan }^{-\,1}}(0.2)\]
Correct Answer: B
Solution :
\[\tan \theta =\frac{qE}{Mg}=\frac{5\times {{10}^{-6}}\times 2\times {{10}^{3}}}{2\times {{10}^{-3}}\times 10}=\frac{1}{2}\] \[\Rightarrow \] \[\theta ={{\tan }^{-1}}\left( \frac{1}{2} \right).\]You need to login to perform this action.
