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.
