A small object of uniform density rolls ...

A small object of uniform density rolls up a curved surface with an initial velocity `v'`. It reaches upto a maximum height of `(3v^(2))/(4g)` with respect to the initial position. The object is

A

ring

B

solid sphere

C

hollow sphere

D

disc

Text Solution

Verified by Experts

The correct Answer is:
D
`(mv^(2))/2+(Iomega^(2))/2=mgxx(3v^(2))/(4g)impliesI=(mR^(2))/2`
for pure rolling condition `v=Romega`
