Question

2.
If units in two systems of measure-
ments are in the ratio 2:3, the ratio of
the units of angular momentum in
those two systems is
1) 2:3 2)9:43) 1:1 494:9​

Answer 1

Answer:

1) 2:3

Explanation:

All units in system one :  those in system two = 1 : 3 (Given)

Units in system one are  1/3 of those in system 2

Angular momentum  =  mass  × angular velocity =  m  × ω

=  mass ×  linear velocity / radius

 =   mass × radians / sec

Thus, momentum 1  =  (2/3)  × (2/3)  /  (2/3)  of system two

AM1 : AM2  =  2/3  or 2:3    Therefore, the ratio will remain the same.

Hence, If the ratio of fundamental units in two systems is 2:3 then the ratio of momentum in the two system is 2:3.
