Question

The physical quantity that has the same dimensional formula as pressure is : (A) Force (B) Momentum (C) Young's modulus of elasticity (D) Coefficient of viscosity

Tardigrade Admin · Accepted Answer

Y =( text stress / text strain ) (Strain is dimensionless) ∴[ Y ]=[ text stress ]=[ text Pressure ]

Q. The physical quantity that has the same dimensional formula as pressure is :

Force

Momentum

Young's modulus of elasticity

Coefficient of viscosity

$Y = \frac{stress}{strain}$ (Strain is dimensionless)
$∴ [Y] = [stress] = [Pressure]$

Q. The physical quantity that has the same dimensional formula as pressure is :

Force

Momentum

Young's modulus of elasticity

Coefficient of viscosity

Y= strain stress ​ (Strain is dimensionless) ∴[Y]=[ stress ]=[ Pressure ]

$Y = \frac{stress}{strain}$ (Strain is dimensionless)
$∴ [Y] = [stress] = [Pressure]$
