A) \[{{10}^{-2}}m\]
B) \[{{10}^{-4}}m\]
C) \[{{10}^{-6}}m\]
D) \[5\times {{10}^{-6}}m\]
Correct Answer: C
Solution :
\[m=\frac{v}{u}=\frac{I}{O}=\frac{f}{u}\] \[\therefore \] \[\frac{I}{5}=\frac{10\times {{10}^{-2}}}{500\times {{10}^{3}}}\] \[\Rightarrow \] \[\mathbf{I=1}{{\mathbf{0}}^{\mathbf{-4}}}\mathbf{m}\]You need to login to perform this action.
