NEET Physics Physical Quantities Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Dimensional analysis | (i) SI unit of energy |
| (b) Kinetic energy formula | (ii) Same dimensions on both sides |
| (c) Consistency check | (iii) Used to deduce relations |
| (d) Energy unit | (iv) K = (1/2)mv^2 |
a-iii, b-iv, c-ii, d-i
a-ii, b-iii, c-i, d-iv
a-iv, b-i, c-iii, d-ii
a-i, b-ii, c-iv, d-iii
Correct Answer
Detailed Explanation
Dimensional analysis is used to deduce relations among physical quantities (a-iii). The correct kinetic energy formula is K = (1/2)mv^2 (b-iv), and a consistency check requires the same dimensions on both sides of an equation (c-ii). The SI unit of energy is indeed Joules (d-i).
