Q. Moment of inertia of circular loop of radius R about the axis of rotation parallel to horizontal diameter at a distance R/2 from it is
System of Particles and Rotational Motion
A
$MR^2$
12%
B
$\frac{1}{2}MR^2$
29%
C
$2MR^2$
17%
D
$\frac{3}{4}MR^2$
41%
Solution:
Applying theorem of parallel axis
$I=I_{CM}+M\left(\frac{R}{2}\right)^2$
$I=\frac{1}{2}MR^2+\frac{MR^2}{4}$
$I=\frac{3}{4}MR^2$
