Question

a body of mass 0.1 kg is rotating about an Axis if the centre of mass of a body is at a distance 0.5 m from the axis of rotation calculate the moment of inertia ​

Answer 1

Answer:

We know angular momentum=Iω---(1) where I= moment of inertia and ω= angular speed

Also moment of inertia I=k

2

m=0.1

2

×10=0.1kgm

2

where k= radius of gyration(0.1 m) and m= mass(10 kg)

Putting the values in equation 1 we get

Angular momentum=0.1×10=1 kg m
