Homework Statement
A bug is sitting on a rotating vinyl record. Between the bug to the record acts static force. for the bug not to lose it's grip and be thrown outside of the record, he should:
a. sit closer to the center.
b. sit further from the center.
c. lose weight.
d. both a and c are correct.
Homework Equations
Centripetal force: F=mw2R
Friction: F=μmg
The Attempt at a Solution
I think the changing the radius will reduce the centripetal force and will not affect the friction. this it will make the bug's grip more firm and will prevent it from losing grip.
although, losing weight will decrease both the centripetal force and the friction at the same ratio. the ratio between them will stay the same. my teacher said the answer is d.
Who is correct??
Thanks for the help!
