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