If the dimensions of a physical quantity are given by M^{a} L^{b} T^{c}, the physical quantity will be
pressure if a = 1, b = -1, c= 2
velocity if a = 1, b = 1, c = -2
acceleration if a = 1, b = 1, c =-2
force if a = 0, b = -1, c =- 2
A.
pressure if a = 1, b = -1, c= 2
Dimensions of velocity = [ M^{0}L^{1}T^{-1}]
Here, a = 0, b =1, c = -1
Dimension of acceleration = [ M^{0}L^{1}T^{-2}]
Dimension of force = [ M^{1}L^{1}T^{-2}]
Dimension of pressure = [M^{1}L^{-1}T^{-2}
The physical quantity is pressure.
