A) Ring
B) Cylinder
C) Spherical shell
D) Solid sphere
Correct Answer: D
Solution :
For solid sphere. K.E. of rotation \[=\frac{1}{2}I{{\omega }^{2}}\] \[\Rightarrow \] \[KEr=\frac{1}{2}\left( \frac{2}{5}m{{r}^{2}} \right){{\omega }^{2}}\] \[\Rightarrow \] \[KEr=\frac{1}{2}m{{\upsilon }^{2}}\] \[\Rightarrow \] \[KEr=40%\] of \[\left( \frac{1}{2}m{{\upsilon }^{2}} \right)\]You need to login to perform this action.
