NEET Physics Centre of Mass Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) CM of two particles | (i) Lies at the midpoint for equal masses |
| (b) CM of a uniform rod | (ii) Lies at the geometric centre |
| (c) CM of an L-shaped lamina | (iii) Lies outside the body itself |
| (d) CM of particles in a triangle | (iv) Coincides with the centroid |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The centre of mass (CM) of two particles lies closer to the heavier particle and is at the midpoint when masses are equal (a-i). For a uniform rod, the CM is located at its geometric centre (b-ii). The CM of an L-shaped lamina can lie outside the body itself (c-iii), and for three particles forming a triangle, the CM coincides with the centroid (d-iv).
