If the dimensions of a physical quantity are given by MᵃLᵇTᶜ, then the physical quantity will be:

1. Velocity if a = 1, b = 0, c = -1
2. Acceleration if a = 1, b = 1, c = -2
3. Force if a = 0, b = 1, c = -2
4. Pressure if a = 1, b = -1, c = -2

Correct answer: Velocity if a = 1, b = 0, c = -1

Solution

The dimensions MᵃLᵇTᶜ with a = 1, b = 0, c = -1 correspond to velocity, as velocity has the dimensional formula [M⁰L¹T⁻¹].
