A small part of the rim of a fly wheel breaks off while it is rotating at a constant angular speed. Then its radius of gyration will
Options
(a) Increase
(b) Decrease
(c) Remain unchanged
(d) Nothing definite can be said
Correct Answer:
Decrease
Explanation:
Iω is conserved. If a small piece is broken. I will be less and ω will increase But I = mk², as I is less, m is small, k² also will be small. The radius of gyration also will decrease.
