QAIPMT-2005-Ph-2545: NEET 2005 Physics - Class 11 AIPMT-2005-Ph-2545 Solution: The moment of inertia of a uniform circular disc of radius R…

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

Multiple Choice Options

A $MR^2$
B $\frac{1}{2}MR^2$
C $\frac{3}{2}MR^2$
D $\frac{7}{2}MR^2$

Step-by-Step Verified Solution

Moment of Inertia of uniform circular disc with radius �R� and mass �M� about axis passing through C.M. and normal to disc will be : I CM = (1/2) MR 2 Moment of Inertia about axis tangential to disc : I T = I CM + MR 2 I T = (1/2) MR 2 + MR 2 = (3/2) MR 2
