The physical quantity which has the dimensional formula $${ M }^{ 1 }{ T }^{ -3 }$$ is:


ANSWER

solar constant


SOLUTION
Surface tension $$\displaystyle \rightarrow \frac{F}{l}=\frac{MLT^{-2}}{L}=MT^{-2}$$

Solar constant $$=MT^{-3}$$

Density $$=\dfrac{Mass}{Vol}=ML^{-3}$$
Compressibillity $$=\dfrac{1}{Bulk \ Modulus}=\dfrac{\dfrac{dv}{v}}{dp}=\dfrac{L^{3}/L^{3}}{ML^{-1}T^{-2}}=M^{-1}L^{1}T^{2}$$

Hence, option B is correct.
