Q. The physical quantity which has the dimensional formula $M^{1}T^{- 3}$ is
A) Surface tension
B) Solar constant
C) Density
D) Compressibility
Explanation
Solar constant is energy received per unit area per unit time i.e. $\frac{\lbrack ML^{2}T^{- 2}\rbrack}{\left\lbrack L^{2} \right\rbrack\lbrack T\rbrack} = {\lbrack M}^{1}T^{- 3}\rbrack$
