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
biryani:
pls pls pls frnds solve it fast.....wid step by step
is ratio given 2:3 or 3:2 ???

All units in system1 : those in system2 = 2 : 3
Units in system 1 are 2/3 of those in system 2
Angular momentum = mass * angular velocity = m * ω
= mass * linear velocity / radius
= mass * radians / sec
Ang momentum 1 = (2/3) * (2/3) / (2/3) of system 2
AM1 : AM2 = 2/3 or 2:3

answer is 9:4....ur answer is wrong
you r right. Angular momentum = Linear momentum * radius of rotation. So it is mass * velocity * radius = mass * distance / time * radius So 2/3 2/3 1/(2/3) 2/3 = 4/9. IT HAS TO BE 4/9. NOT 9/4.
