A mass $M$ is supported by a mass less string would wound a uniform cylinder of mass $M$ and radius $R$. On releasing the mass from rest, it will fall with acceleration
$g$
$\frac{g}{2}$
$\frac{g}{3}$
$\frac{{2g}}{3}$
Explain translational motion by given illustration.
What is rigid body?
Two hollow spheres each of mass $M$ and radius $\frac {R}{2}$ are connected with a massless rod of length $2R$ as shown in figure. What will be the moment of inhertia of the system about an axis $yy'$ passing through the center of one of the sphere and perpendicular to the rod
What is rotational motion and axis ?
"A particle has point volume". True of False ?
