A unifrom semicircular disc is suspended from a point C on it such that it remains in vertical plane. It is found that point C is such that disc remains in equilibrium in every orientation. What is distance OC ?

A

1 m

B

1.5 m

C

1.33 m

D

1.83 m

Text Solution

Verified by Experts

The correct Answer is:
C
To remain in equilibrium C must be CM of semicircular disc.
`( :. I_(Mg) = 0)`
So `OC = (4R)/(3pi) = 1.33 m`
