Physics - Center of Mass Question with Solution | TestHub
Statement-1 : If a uniform circular disc has a circular hole cut out from its edge, the center of mass of the remaining portion shifts away from the center of the original disc, in the direction opposite to the hole.
Statement-2 : The center of mass of a system of particles is given by .
Options:
Answer:
Solution:
Statement-1 is true. When a part is removed from a uniform body, the center of mass of the remaining portion shifts away from the removed part. If a hole is cut from the edge, the remaining mass is concentrated on the opposite side, causing the COM to shift in that direction. Statement-2 provides the general formula for the center of mass, which is fundamental to calculating such shifts. Therefore, Statement-2 correctly explains the principle behind Statement-1.
