2 masses of mass m each are rigidly attached to two rigid rods as shown and this setup perforfms UCM,
then
A)both the masses have same angular velocity
B)if the rods are mass less, both the masses will experience same centrifugal force
C)both masses will have same speed
D)the velocity of outward mass will be double that of inward force

Answer:
Given,
Both objects have mass =M
The separation between them =L
Both objects has equal mass, canter of mass will be at the axis.
Distance of object from center of mass d=
2
L
Moment of Inertia = Mass X (Distance from axis)2
Total moment of Inertia = Moment of Inertia of object 1 + Moment of Inertia of object 1
