The dimensions of Solar Constant (energy falling on unit area per unit time) are:
Options
Option A is correct
[M¹ L⁰ T⁻³]
Option B
[M¹ L² T⁻²]
Option C
[M¹ L¹ T⁻²]
Option D
[M¹ L⁰ T⁻²]
Explanation
Solar constant = Energy / (Area × Time) = [ML²T⁻²] / ([L²][T]) = [ML⁰T⁻³]. [ML²T⁻²] is energy, [ML¹T⁻²] is force, and [ML⁰T⁻²] is surface tension/spring constant. These do not represent energy per area per time.
