Physics

Match the following.
List IList II
A.Angular momentum1.$$[M^{-1}L^2T^{-2}]$$
B.Torque2.$$[M^1T^{-2}]$$
C.Gravitational constant3.$$[M^1L^2T^{-2}]$$
D.Tension4.$$M^1L^2T^{-1}]$$


ANSWER

A-4, B-3


SOLUTION
$$\left[ L \right] ={ M }^{ 1 }{ L }^{ 2 }{ T }^{ -1 }\\ \left[ \tau  \right] ={ M }^{ 1 }{ L }^{ 2 }{ T }^{ -2 }\\ \left[ G \right] ={ M }^{ -1 }{ L }^{ 3 }{ T }^{ -2 }\\ \left[ T \right] ={ M }^{ 1 }{ L }^{ 1 }{ T }^{ -2 }$$
