A big dumb-bell is prepared by using a uniform rod of mass 60 g and length 20 cm. Two identical solid thermocol spheres of mass 25 g and radius 10 cm each are at the two ends of the rod. Calculate moment of inertia of the dumb bell when rotated about an axis passing through its centre and perpendicular to the length.
As per the given condition we can list out the data as mass of rod = M= 60g length of…
