If the dimensions of a physical quantity are given by Ma Lb Tc, 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 Option: D

Pressure =	[MLT^-2]	= ML^-1T^-2
	[L²]

⇒ a = 1, b = – 1, c = – 2.
