Title: FORCE & PRESSURE – NUMERICALS (Part : 2)
Question:5
A normal force of 200 N acts on an area of 0.02 m². Find the pressure in pascal.
Solution:
Given:
Force, F = 200 N
Area, A = 0.02 m²
Pressure, P = ?
Formula:
Pressure = Force / Area
P=F/A
Substitution:
P = .02
To remove the decimal, multiply top and bottom by 100:
P = (200 × 100) / (0.02 × 100)
P =
P = 10000 Pa
Final Answer:
Pressure = 10000 Pa
Question: 6
Find the thrust required to exert a pressure of 50,000 pascal on an area of 0.05 m².
Solution:
Given :
Pressure, P = 50,000 Pa
Area, A = 0.05 m²
Thrust (Force), F = ?
Formula :
