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

A

Doubled

B

Tripled

C

Quadrupled

D

8 times the original value

Verified by Experts

The correct Answer is:

C

Angular momentum
L = mrv = mass = `("length")^2 xx ("sec")^(-1)`
New angular momentum `= [(2M)(2L)^(2)(2T)^(-1)]`
`= 4[ML^(2)T^(-1)] = 4L `.
