A) \[T\propto {{r}^{2}}\]
B) \[T\propto r\]
C) \[{{T}^{2}}\propto {{r}^{3}}\]
D) \[T\propto \sqrt{r}\]
Correct Answer: B
Solution :
\[F=\left( \frac{k}{r} \right)m\]k is some constant so \[\frac{m{{v}^{2}}}{r}=\frac{km}{r}\Rightarrow v=\]constant \[T=\frac{2\pi r}{v}\] \[T\propto r\]straight lineYou need to login to perform this action.
