If the dimensions of a physical quantity are givenby Mᵃ Lᵇ Tᶜ, then the physical quantity will be:

Options

(a) Velocity if a= 1, b = 0, c = – 1
(b) Acceleration if a= 1, b = 1, c = – 2
(c) Force if a = 0, b = – 1, c = – 2
(d) Pressure if a = 1, b= – 1,c = – 2

Correct Answer:

Pressure if a = 1, b= – 1,c = – 2

Explanation:

Pressure = MLT⁻² / L² = ML⁻¹T⁻²
⇒ a= 1, b= -1, c= -2.
