Understanding the Dimension of Pressure
Asked by Aaradhya Patel · 2 years ago
Can someone explain the dimension of pressure in simple terms? I'm preparing for the NEET exam and need a clear understanding based on the NCERT syllabus.

Sure! According to the NCERT syllabus, pressure is defined as the force exerted per unit area. To find the dimension of pressure, we need to understand the dimensions of force and area.
Force (F) has the dimension [M L T-2], where:
- M is mass
- L is length
- T is time
Area (A) has the dimension [L2], since it is length times length.
Therefore, the dimension of pressure (P) is given by:
P = F / A
= [M L T-2] / [L2]
= [M L-1 T-2]
So, the dimension of pressure is [M L-1 T-2]. Hope this helps!
