A particle of mass `1 kg` is moving alogn the line `y=x+2` with speed `2m//sec`. The magnitude of angular momentum of the particle about the origin is

A

`4 kg -0 m^(2)`/sec

B

`2sqrt(2)kg -m^(2) /sec`

C

`4sqrt(2)kg -m^(2)`/sec

D

`2kg - m^(2) b`/sec

Text Solution

Verified by Experts

The correct Answer is:
B

` L = mvr_(bot) = 1(2) (2 cos 45^(@)) = 2sqrt(2)`
