Question

The SI unit of pressure can correctly be represented as
Nm-2
N/m/m
Newton/m/m
N/metre/metre​

Answer 1

Answer:

N/m^2 : newton /meter^2 =force /area=N/m^2

Answer 2

The SI unit of pressure can be represented as Nm⁻²

• Pressure can be mathematically expressed as :

Pressure = Force / Area

• Now, SI unit of force is = Newton (N)
• And, SI unit of area is = m²
• So, SI unit of pressure will be :

= SI unit of force / SI unit of area

= N / m²

= Nm⁻²

• This, Nm⁻² is the only correct representation of the SI unit of pressure, among the given options. Rest of the given options are absolutely wrong representations.
• Additional data : One Nm⁻² is equivalent to One Pascal (1 Nm⁻² = 1 Pascal). And, this Pascal unit is commonly used in the practical world.
