A disc of mass `m` and radius `R` moves in the `x-y` plane as shown in Fig. The angular momentum of the disc about the origin `O` at the instant shown is

A

`5/2 mR^(2) omega`

B

`7/2 mR^(2)omega`

C

`9/2 mR^(2) omega`

D

`3/2 mR^(2) omega`

Text Solution

Verified by Experts

The correct Answer is:
A
`I=mv(3R)(-hatk) + 1/2 mR^(2)omega hatk` and `V=Romega = -5/2 mr^(2) omega hatk`
