1.	A particle of mass 5 kg is moving with a uniform speed of 3 sqrt(2) "cm s"^(-1) in the XY-plane along the line y = 2 sqrt(5) cm. The magnitude of its angular momentum about the origin in "g-cm"^(2) s^(-1) is
Answer» zero 30 `30 sqrt(2)` `30 sqrt(10)` Solution :The angular momentum, `L=mr_(1)=(5)(3 sqrt(2))(2 sqrt(5))` `=30 sqrt(10)"g-cm"^(2)s^(-1)`
