A) \[r{{t}^{2}}\]
B) \[rt\]
C) \[{{r}^{2}}t\]
D) \[r/t\]
Correct Answer: C
Solution :
\[\frac{{{v}^{2}}}{r}=r{{t}^{2}}\Rightarrow v=rt\] \[P=\overset{\to }{\mathop{F}}\,\,\,.\,\,\overset{\to }{\mathop{v}}\,\,=\left( \frac{mdv}{dt} \right)v\] \[=(mr)rt\] \[P\,\propto \,{{r}^{2}}t\]You need to login to perform this action.
