Three rods each of length L and mass M are placed along X , Y and Z -axes in such a way that one end of each of the rod is at the origin. The moment of inertia of this system about Z axis is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Moment of inertia of the system about z- axis can be find out by calculating the moment of inertia of individual rod about z -axis
because z -axis is the edge of rod 1 and 2 and 
because rod in lying on z -axis
.
