Pressure gradient has the same dimension as that of

View answer and explanation

Correct option: D

None of these

Option D (None of these) is correct because pressure gradient has dimensions of [ML⁻²T⁻²], velocity gradient has dimensions of [T⁻¹], and potential gradient has dimensions of [MLT⁻³A⁻¹], and energy gradient has dimensions of [ML²T⁻²L⁻¹] = [MLT⁻²], so none match.
