Which of the following is the unit of pressure?

Correct answer: B. Kg m-1 s-2

  • A. Kg m s-1
  • B. Kg m-1 s-2
  • C. Kg m2 s-2
  • D. Kg m-2 s-1

Explanation

Pressure is calculated as force per unit area. In this case, the correct unit of pressure is Kg m-1 s-2. This unit is derived from the formula P = F/A, where force is measured in Kg m s-2 and area in m2. This simplifies to Kg m-1 s-2, which is the unit of pressure.Option A is incorrect as it represents the unit of momentum, not pressure. Option C is also incorrect as it represents the unit of energy or work. Option D is not the unit of pressure either.

About Physical Quantities and Units

Physical quantities combine a numerical value with a unit, and are expressed using SI base units or derived units such as newtons, joules and pascals. The topic covers prefixes, unit conversion, dimensional analysis, significant figures and measurement uncertainty, while distinguishing scalar quantities from vectors where direction matters.
