Question

a uniform semicircular disc has radius R, the distance of center of mass from center 'O' is

Answer 1

Step-by-step explanation:

If we consider the circular disc we see that its mass is 2M and its moment of inertia about the center would be

2

(2M)R

2

=MR

2

Thus moment of inertia of half of this disc would be

2

MR
