A uniform circular disc has a radius of 20 cm. A circular disc of radius 10 cm is cut concentrically from the original disc. The shift in the centre of mass is

View answer and explanation

Correct option: D

Zero

Option D is correct. Since the circular disc is cut concentrically, the center of mass remains at the same location, which is the center of the disc. Therefore, the shift in the center of mass is zero.
