A disc of mass m and radius r lies in x-y plane with its centre at a distance 'a' from origin at (a, 0) then -
A
Its moment of inertia about x-axis is 
B
Its moments of inertia about y-axis is 
+ ma 2
+ ma 2
C
Its moments of inertia about z-axis 
+ ma 2
+ ma 2
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, b, c)
As x-axis is along diameter ∴ I x = 
mr 2
And I y = 
+ 
using parallel axis theorem
I z = 
+ ma 2
