A) \[{{\tan }^{-1}}(5.0)\]
B) \[{{\tan }^{-1}}(2.0)\]
C) \[{{\tan }^{-1}}(0.5)\]
D) \[{{\tan }^{-1}}(0.2)\]
Correct Answer: C
Solution :
[c] |
\[\tan \theta =\frac{qE}{mg}=\frac{5\times {{10}^{-6}}\times 2000}{2\times {{10}^{-3}}\times 10}\] |
\[\tan \theta =\frac{1}{2}\Rightarrow \,\theta ={{\tan }^{-1}}(0.5)\] |
