A) 1 : 2
B) \[1:2\sqrt{2}\]
C) 1 : 4
D) \[1:\sqrt{2}\]
Correct Answer: B
Solution :
\[{{V}_{e}}=\sqrt{\frac{2GM}{R}}=\sqrt{\frac{2G}{R}.\left( \frac{4}{3}\pi {{R}^{3}}\rho \right)}\propto R\sqrt{\rho }\] \[\therefore \]\[\text{Ratio}\,\,\text{=}\,\,1:2\sqrt{2}\]You need to login to perform this action.
