A unit mass at position vector `vecr=(3hati+hatj)` is moving with velocity `vecv=(5hati-6hatj)`. What is the angular momentum of the body about the origin?

A particle of mass 0.01 kg having position vector vecr = ( 10 hati + 6 hatj) meters is moving with a velocity 5 hati m/s . Calculate its angular momentum about the origin.

A unit mass has vecr=8hati-4hatj and vecv=8hati+4hatj What is its angular momentum ?

A partical has the position vector r = hati - 2 hatj + hatk and the linear momentum p = 2 hati - hatj + hatk its angular momentum about the origin is

Convert the vector vecr=3hati+2hatj into a unit vector.

The position vector vecr and linear momentum vecp and vecr=hati and vecp=4hatj the angular momentum vector is perpendicular to
