Match List I with II and select the correct answer:
List-IList-II
A.Spring constant1. $${ M }^{ 1 }{ L }^{ 2 }{ T }^{ -2 }$$
B.pascal2. $${ M }^{ 0 }{ L }^{ 0 }{ T }^{ -1 }$$
C.hertz3. $${ M }^{ 1 }{ L }^{ 0 }{ T }^{ -2 }$$
D.joule 4.$${ M }^{ 1 }{ L }^{ -1 }{ T }^{ -2 }$$


ANSWER

A-3, B-4, C-2, D-1


SOLUTION
Spring constant dimensions will be $$K=\dfrac{F}{X}=\dfrac{MLT^{-2}}{L}=ML^0T^{-2}$$

Pascal is unit of pressure $$\dfrac{F}{A}=\dfrac{MLT^{-2}}{L^2}=ML^{-1}T^{-2}$$

Hertz is frequency $$=\dfrac{1}{t}=T^{-1}$$

Joule is unit of energy so dimension is $$ML^2T^{-2}$$
