Provided that:
- Weight = Force = 1000 = 10³ N
- Pressure = 10000 = 10⁵ Pa
To calculate:
- Area of contact
Solution:
- Area of contact = 10-² = 0.01 m
Using concept:
- Pressure formula
Using formula:
- Pressure = Force/Area
Required solution:
↦ Pressure = Force/Area
↦ P = F/A
↦ 10⁵ = 10³/A
↦ A = 10³/10⁵
↦ 10^3-5 m = A
↦ 10-² m = A
↦ Area of contact = 10-² m
↦ Area of contact = 0.01 m
- Henceforth, area of contact = 10-² metres or 0.01 metres.

Given:
A solid weighing 1000 N exerts a pressure of 10⁵ Pa when placed on table.
To find:
Area of contact?
Calculation:
- Pressure is a scalar quantity and is defined as the ratio of perpendicular force (or thrust) and surface area of contact.
So, area of contact is 0.01 m².
