Question

The dimensions ML⁻¹ T⁻² may correspond to

Options

• work done by a force

•  linear momentum

•  pressure.

•  energy per unit volume.

Answer 1

pressure
energy per unit volume

[Work done] = [ML²T⁻²]
[Linear momentum] = [MLT⁻¹]
[Pressure] = [ML⁻¹ T⁻²]
[Energy per unit volume] = [ML⁻¹ T⁻²]

From the above, we can see that pressure and energy per unit volume have the same dimension, i.e., ML⁻¹ T⁻².
