A mass is whirled in a circular path with constant angular velocity and its angular momentum is. If the string is now halved keeping the angular velocity the same, the angular momentum is
Options:
Answer:
A
Solution:
L = mr2ω. For given m and ω, L ∝ r2. If r is halved, the angular momentum L becomes one-fourth.
