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

A

`9.8"kgm"^(2)//s`

B

Zero

C

`52.7"kgm"^(2)//s`

D

`37.9"kgm"^(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`
