The centre of mass of a body
Is always outside the body
May lie inside or outside the body
Lies inside the body
Always lies on the surface of the body
Radius of gyration of a body depends on
A tube of length $L$ is filled completely with an incompressible liquid of mass $M$ and closed at both the ends. The tube is then rotated in a horizontal plane about one of its end with a uniform angular velocity $\omega$. The force exerted by the liquid at the other end is
Four masses are fixed on a massless rod as shown in Fig. The moment of inertia about the axis $P$ is about ....... $kg-m^2$
In the given figure linear acceleration of solid cylinder of mass $m_2$ is $a_2$ . Then angular acceleration $\alpha_2$ is (given that there is no slipping)
In an experiment with a beam balance an unknown mass $m$ is balanced by two known masses of $16\,kg$ and $4 \,kg$ as shown in figure. The value of the unknown mass $m$ is ......... $kg.$
