A system consists of two identical spheres each of mass1.5 kgand radius50 cmat the ends of a light rod. The distance between the centres of the two spheres is5 m.What will be the moment of inertia of the system about an axis perpendicular to the rod passing through its midpoint?

Question diagram: A system consists of two identical spheres each of mass 1 .

Options:

Answer:
C
Solution:


I=25MR2+Mx2×2=25×1.5×0.52+1.5×2.52×2=[0.15+9.375]×2=19.05kgm2
