MHT CET Physics question

A uniform metal rod of length 1 m is bent at , so as to form two arms of equal length. The centre of mass of this bent rod is

(A)on the bisector of the angle, m from vertex
(B)on the bisector of the angle, m from vertex
(C)on the bisector of the angle, m from vertex
(D)on the bisector of the angle, m from vertexCorrect

Answer: (D)

Solution

Each arm is 0.5 m with its CM at 0.25 m from the vertex, so the combined CM is the midpoint of the line joining these two points, i.e. at m, a distance
