Physics-Physical Quantities
NEET Physics Physical Quantities Match the Following Question
Type: Match the Following-match the column-Medium-Class 11
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
Choose the correct matching:
A
a-iii, b-iv, c-ii, d-i
B
a-ii, b-iii, c-i, d-iv
C
a-iv, b-i, c-iii, d-ii
D
a-i, b-ii, c-iv, d-iii
Correct Answer
Option A
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).
