A particle of mass m=5 units is moving with uniform speed `V=3sqrt2` units in the XY plane along the line Y = X + 4. The magnitude of the angular momentum about origin is,

A

Zero

B

60 units

C

7.5 units

D

40 units

Text Solution

Verified by Experts

The correct Answer is:
(b)
`L=mvrcostheta`
`m=5`units,`v=3sqrt2`,`r=4,theta=45^(@)` (Given)
`L=5xx3sqrt2xx4xx(1)/(sqrt2)`
because `L=60` units.
