The dimensions of Solar Constant (energy falling on unit area per unit time) are:

Model Answer & Options

Source: Extra Practice

[M¹ L⁰ T⁻³]

[M¹ L² T⁻²]

[M¹ L¹ T⁻²]

[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.
