Circular MotionHard
Question
A coin placed on a rotating turntable just slips if it is placed at a distance of 16 cm from the centre. If the angular velocity of the turntable is doubled, it will just slip at a distance of
Options
A.1 cm
B.2 cm
C.4 cm
D.8 cm
Solution
For just slip ⇒ μmg = mω2r
here ω is double then radius is 1/4th
r′ = 4 cm Ans.
here ω is double then radius is 1/4th
r′ = 4 cm Ans.
