Question

find the dimension of pressure​

Answer 1

Answer:

Substituting these values of dimension of Force and area, we get the dimensional formula of Pressure as dimensional formula of Pressure = [M 1L1T −2] [M 0L2T 0] = [M 1L−1T −2] dimensional formula of Pressure = [ M 1 L 1 T − 2] [ M 0 L 2 T 0] = [ M 1 L − 1 T − 2] Pressure is denoted by Letter P P

Answer 2

Answer:

M L-1 T-2

Explanation:

Pressure (P) = Force × Area-1 . . . . . (1)

Since, Force = Mass × Acceleration

And, acceleration = velocity × time-1 = [L T-1] [T]-1 = [L T-2]

∴ The dimensional formula of force = [M] × [L T-2] = Force = M1 L1 T-2 . . . . (2)

The dimensional formula of area = M0 L2 T0 . . . . (3)

On substituting equation (2) and (3) in equation (1) we get,

Pressure (P) = Force × Area-1

Or, P = [M1 L1 T-2] × [L2]-1 = M1 L-1 T -2.

Therefore, the pressure is dimensionally represented as M1 L-1 T -2.
