A wheel has mass of the rim 1 kg, having 50 spokes each of mass 5g. The radius of the wheel is 40 cm. The moment of inertia is

A

0.273 kg `m^(2)`

B

1.73 kg `m^(2)`

C

0173 kg `m^(2)`

D

2.73 kg `m^(2)`

Text Solution

Verified by Experts

c) l =` mr^(2) + 50 (ml^(2))/3`
`= 1 xx (0.4)^(2) + (50(5 xx 10^(-3))(0.4)^(2))/3`
`0.16(1.083) =0.173kgm^(2)`
