A) 110 \[km\,{{s}^{-1}}\]
B) 0.11 \[km\,{{s}^{-1}}\]
C) 1.1 \[km\,{{s}^{-1}}\]
D) 11 \[km\,{{s}^{-1}}\]
Correct Answer: A
Solution :
\[\frac{{{V}_{1}}}{{{V}_{2}}}=\sqrt{\frac{{{M}_{1}}}{{{M}_{2}}}\times \frac{{{R}_{2}}}{{{R}_{1}}}}\] \[{{V}_{1}}={{V}_{2}}\sqrt{\frac{{{M}_{1}}}{{{M}_{2}}}\times \frac{{{R}_{2}}}{{{R}_{1}}}}=11\left( km/s \right)\times \sqrt{10\times 10}\]\[=110\,km/s\]You need to login to perform this action.
