Two particles A and B are moving as shown in figure. Their total angular momentum about the point O is

A

`9.8 kg m^(2)//s`

B

zero

C

`52.7 kg m^(2)//s`

D

`37.9 kg m^(2)//s`

Text Solution

Verified by Experts

The correct Answer is:
A
`vec(L) = (6.5) (2.2) (1.5) (- hat(k)) + (2.8) (3.1) (3.6) (hat(k))`
`= 9.8 (hat(k)) kg- m^(2)//s`
