Per NCERT Ex 6.1, three particles of mass 100 g, 150 g, 200 g sit at the vertices of an equilateral triangle. The CM coincides with the centroid?
AYes, irrespective of mass
BNo, the CM is shifted toward the heavier mass
CNo, the CM is exactly at the lightest mass
DYes, always at the centroid
Answer & Solution
Correct answer: B. No, the CM is shifted toward the heavier mass
NCERT Ex 6.1: only for equal masses is the CM at the centroid. With unequal masses the CM shifts toward the heavier vertex.
