AIPMT PRELIMS 2005 Physics Moment of Inertia MCQ Question
Type: MCQ-numerical-Medium-Class 11
The moment of inertia of a uniform circular disc of radius R and mass M about an axis passing from the edge of the disc and normal to the disc is:
A
(5/2)MR²
B
MR²
C
(7/2)MR²
D
2MR²
Correct Answer
Option D
Detailed Explanation
Using the parallel axis theorem, I = I_cm + MR² = (1/2)MR² + MR² = (3/2)MR² + MR² = (7/2)MR².
