NEET Physics Centre of Mass Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Centroid of an equilateral triangle | (i) Lies at L/2 from either end |
| (b) CM of a uniform thin rod | (ii) Lies on the medians |
| (c) CM of a triangular lamina | (iii) Lies outside the body |
| (d) CM of an L-shaped lamina | (iv) CM coincides with the centroid |
a-i, b-ii, c-iv, d-iii
a-iv, b-i, c-ii, d-iii
a-ii, b-iv, c-i, d-iii
a-iii, b-ii, c-iv, d-i
Correct Answer
Detailed Explanation
The centroid of an equilateral triangle coincides with its center of mass (CM), which is at the centroid (a-iv). The CM of a uniform thin rod is at L/2 from either end (b-i). The CM of a triangular lamina lies on the medians (c-ii). The CM of an L-shaped lamina can lie outside the body itself (d-iii).
