A particle undergoes uniform circular motion. The angular momentum of the particle remain conserved about:

Answer»

the centre point of the circle
the point on the circumference of the circle
any point inside the circle
any point OUTSIDE the cicle

Solution :`VECL=vecrxxvecP`
`vecL=vecrxxmvecv`
`vecL=` Constant
when `VECR` and `VECV=` Constant
