$A$ uniform cylinder of mass $m$ can rotate freely about its own axis which is horizontal.$A$ particle of mass mo hangs from the end of a light string wound round the cylinder which does not slip over it. When the system is allowed to move, the acceleration of the descending mass will be
$\frac{{2{m_o}g}}{{m + 2{m_o}}}$
$\frac{{{m_o}g}}{{m + {m_o}}}$
$\frac{{2{m_o}g}}{{m + {m_o}}}$
$\frac{{{m_o}g}}{{2m + {m_o}}}$
What is the total momentum of the system of particle ?
State and explain the law of conservation of momentum of the system of particle.
Difference between rigid body and solid body.
Write the Newton's second law for rotational motion about a fixed axis.
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
