Question

) If units of two systems of measurements are in the ratio 3:4 then ratio of units of angular momentum In those twosystems is1) 2:3 2) 9:43) 1:14) 4:9​

Answer 1

Answer:

4:9

Explanation:

The correct question statement is;

If units in two systems of measurements are in the ratio 2:3,the ratio of the units of angular momentum in those two system is

1. 2:3

2. 9:4

3. 1:1

4. 4:9

Solution

Among the four options given in question statement, the correct option is the last one.

Angular momentum = Inertia x Angular velocity

Here we can see that angular momentum is actual the product of two terms. Hence of the units of systems each have their measurements ( i.e inertia and angular velocity) have the ration of 2:3 to the other system, then angular momentum ratios would be;

2:3 x 2: 3 = 4:9

Answer 2

Thus the ratio of angular momentum in those two systems is 4 : 9

Explanation:

Correct statement:

If units of two systems of measurements are in the ratio 2:3 then ratio of units of angular momentum In those two systems is?

We are given that:

Measurements of two systems = 2 : 3

Solution:

M1 / M2 = L1 / L2 = T1 / T2 = 3 : 4  

Angular momentum = [ML^2T−1]

Since:

M1L^12T1^−1  / M2L2^2T2T−1

= (M1 / M2) × (L1 / L2)^2 (T2 / T1)

= 3 / 4 ( 2 / 3 )^2 x 4 / 3

= 4 : 9

Thus the the ratio of angular momentum in those two systems is 4 : 9
