A particle of mass 1 kg is moving along ...

A particle of mass 1 kg is moving along the line `y = x + 2` (here x and y are in metres) with speed `2 m//s`. The magnitude of angular momentum of paticle about origin is -

Text Solution

Verified by Experts

`L=m v r_bot` Where `r_bot=(|0-0+2|)/sqrt(1^2+1^2)=sqrt2L= (1kg)(2m/s)(`sqrt2m`), L=`2sqrt2kgm^2/s`.
