MCQ
The physical quantity which has the dimensional formula ${M^1}{T^{ - 3}}$ is
- ASurface tension
- ✓Solar constant
- CDensity
- DCompressibility
✓
Answer
Correct option: B.
Solar constant
b
(b) Solar constant is energy received per unit area per unit time i.e. $\frac{{[M{L^2}{T^{ - 2}}]}}{{[{L^2}]\;[T]}} = [{M^1}{T^{ - 3}}]$
(b) Solar constant is energy received per unit area per unit time i.e. $\frac{{[M{L^2}{T^{ - 2}}]}}{{[{L^2}]\;[T]}} = [{M^1}{T^{ - 3}}]$
