Question

If the unit of mass length and time are doubled unit of angular momentum will be??

Answer 1

L = mvr

L’ = (2m)(v)(2r) = 4L

Answer 2

The new angular momentum becomes four times of the initial angular momentum.

Explanation:

The angular momentum of an object is given by :

$L=mvr$

m is mass

v is velocity

r is distance

It is mentioned that, if the unit of mass length and time are doubled such that,

$L'=(2m)\times v\times (2r)\\\\L'=4\times mvr\\\\L'=4\times L$

So, the new angular momentum becomes four times of the initial angular momentum.
