A) \[T/{{R}^{2}}\] is a constant
B) \[TR\] is a constant
C) \[{{T}^{2}}/{{R}^{3}}\] is a constant
D) \[T/R\] is a constant
Correct Answer: D
Solution :
\[m=\int\limits_{0}^{R}{\rho }4\pi {{r}^{2}}dr\] \[m=4\pi KR\] \[\text{v}\propto \sqrt{4\pi K}\] \[\frac{T}{R}=\frac{2\pi }{\sqrt{4\pi K}}.\]You need to login to perform this action.
