If units of measurement of two system are in the ratio 2 : 1, then the ratio of units of angular momentum in the two system willl be :

Answer

4

Explanation

Here, `(M_1)/(M_2) = (L_1)/(L_2) = (T_1)/(T_2) = (2)/(1)`
Angular momentum `=[ML^2 T^(-1)]`
`:. (M_1 L_1^2 T_1^(-1))/(M_2 L_2^2 T_2T^(-1)) = ((M_1)/(M_2))xx((L_1)/(L_2))^2((T_2)/(T_1))`
`=(2)/(1) ((2)/(1))^2 xx(1)/(2)= 4`
