NEET Physics Centre of Mass Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Centre of Mass of two particles | (i) Lies at the midpoint for equal masses |
| (b) Centre of Mass of a uniform thin rod | (ii) Lies at the geometric center |
| (c) Centre of Mass of a triangular lamina | (iii) Lies on the medians |
| (d) Centre of Mass of an L-shaped lamina | (iv) Lies at (5/6, 5/6) m |
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 of two particles is indeed at the midpoint for equal masses (a-i). For a uniform thin rod, the centre of mass lies at the geometric center (b-ii). The centre of mass of a triangular lamina lies on the medians (c-iii), and for the L-shaped lamina, the calculation yields coordinates (5/6, 5/6) m (d-iv).
