Two particles of masses my = 1 kg and m2 = 2 kg are connected by a rigid rod of length L = 1.2 m and of negligible mass. The system rotates about an axis perpendicular to the rod and at a distance 'x' from the mass m1, and the moment of inertia of the system is I. Then
1
I will be minimum at x= 0.8 m. 16
2
I cannot have a maxima between x = 0 and x = L.
3
Minimum value of I is 0.96 kg-m2.
4
1=1.44 kg-m2 when x=0.
