A) 6.45
B) 4.45
C) 10
D) 8.75
Correct Answer: A
Solution :
According to Kepler?s law \[\frac{T_{1}^{2}}{T_{2}^{2}}=\frac{R_{1}^{3}}{R_{2}^{3}}\Rightarrow \frac{24\times 24}{T_{2}^{2}}=\frac{6\times 6\times 6\times {{R}^{3}}}{2.5\times 2.5\times 2.5\times {{R}^{3}}}\] \[\Rightarrow T_{2}^{2}=\frac{24\times 24\times 2.5\times 2.5\times 2.5}{6\times 6\times 6}=6.45\,\,Hour\]You need to login to perform this action.
