As per your syllabus, the centre of mass of THREE equal masses placed at the vertices of a triangle lies at which point?
AAny vertex
BThe centroid
CThe circumcentre
DThe orthocentre
Answer & Solution
Correct answer: B. The centroid
Your syllabus: equal masses at triangle vertices ⇒ X = (x₁+x₂+x₃)/3, same as centroid.
