Question

Q19. A pressure of 10 kPa acts on an area of 0.3 m². The force acting on the area will be: (1) 3000 N (2) 30 N (33N (4) 300 N
solution: Pressure: 10 kpa =10 × 1000= 10000 Pascal.
Area = 0.3 m^2
Pressure=force/area of contact
10000 Pascal = Force/0.3m^2
Force= 10000 p / 0.3m^2
Force= 10000×3/10
Force= 3000 N

Answer 1

Answer:

We can calculate pressure using the formula, pressure = force / area. In this case, pressure = 10 kPa = 10 * 1000 = 10000 Pa and area = 0.3 m2. So we can find force as follows: Force = Pressure * area = 10000 * 0.3 = 3000 Newtons.

(1) 3000N
