medium
Amount of solar energy received on the earth's surface per unit area per unit time is defined a solar constant. Dimension of solar constant is
A$ML ^{2} T ^{-2}$
B$MLT ^{-2}$
C$M ^{2} L ^{0} T ^{-1}$
D$ML ^{0} T ^{-3}$
(JEE MAIN-2020)
Solution
$S=\frac{E}{A\times t}=\frac{M L^{2} T^{-3}}{L^{2}}=M T^{-3}$
