A cube of mass m and side a is movingf alongg a plane with constant speed `v_(0)` as shown in figure. The magnitude of angular momentum of the cube about z-axis would be

A

`(mv_(o)b)/(2)`

B

`(sqrt3mv_(o)b)/(2)`

C

`mv_(o)(b - (a)/(2))`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
`r_(1) = (b - a)sin30^(@)`
`= ((b -a)/(2))`
`:. L = mv_(o)r_(2) = (mv_(o)(b - a))/(2)`
