Question

2.
(
A block of mass m = 5 kg is kept on rough
horizontal disc at a distance 2 m from the centre
as shown. The coefficient of friction between the
block and the disc is u = 0.8. If the disc is under
uniform circular motion then its angular speed
just above which the block will start sliding is
4.
2 mg
(1) 0.25 rad/s
(3) 1 rad/s
(2) 0.5 rad/s
(4) 2 rad/s​

Answer 1

Explanation:

the max angular speed above which the block starts sliding is sloved above
