» Rotational Motion » Concepts of Rotational Motion
Question
A disc is rolling (without slipping) on a horizontal surface. C is its centre and Q and P are two points equidistant from C. Let V _{P}, V _{Q} and V _{C} be the magnitude of velocities of points P, Q and C respectively, then

» Rotational Motion » Moment of Inertia
Question
From a uniform wire, two circular loops are made (i) P of radius r and (ii) Q of radius nr. If the moment of inertia of loop Q about an axis passing through its center and perpendicular to its plane is 125 times that of P about a similar axis, the value of n is (diameter of the wire is very much smaller than r or nr)
