Question

Name the physical quantity related to the following unit: Pascal.
A. Force
B. Pressure
C. Work
D. Distance

Answer 1

Hint: The given unit is named after the physicist Blaise Pascal for his contribution in physics.
Recall the units of every given physical quantity.

Complete step by step answer:
Given unit is the unit of the given physical quantities. Therefore, we need to check the unit of every given physical quantity.

Force
Force is the product of mass of the body and acceleration produced in the mass of the body. The mass has unit kg and acceleration has unit m/$s^2$. Therefore, the unit of the force is kgm/$s^2$. This unit is also known as Newton.
Therefore, the option (A) is incorrect.

Pressure
Pressure is force divided by area of cross section. The unit of force is N and the unit of area is $m^2$.
Therefore, the unit of pressure is N/$m^2$. This unit is also known as Pascal.
Pascal is the S.I. unit of Pressure.

Work
The work is the product of force and displacement. Therefore, the unit of work is Nm. This unit is also known as Joule.
Joule is the S.I. unit of work and energy.
Therefore, the option (C) is incorrect.

Distance
The S.I. the unit of distance in meters. Therefore, the option (D) is incorrect.

So, the correct answer is “Option B.

Note:
Pascal is the S.I. unit of pressure named after the physicist Blaise Pascal.
Pressure is force divided by area of cross section.
It is also the S.I. unit of stress, Young’s modulus, tensile strength.
