Correct Answer - Option 2 : Pascal(Pa)
Option 2 is correct, i.e. Pascal Pa.
● SI unit of pressure is ‘Pascal’ and it is denoted by Pa.
● The pressure is defined as the force per unit area (pressure = force/area).
● 1 Pascal equals the pressure of 1 newton per square meter and the formula is as follows: 1 Pa = 1N/m2 = 1 kg/m.
● The pascal is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength.
● It is named after the French polymath Blaise Pascal.
