Q58 of 176 Page 125

Calculate the pressure when a force of 200 N is exerted on an area of:
(i) 10 m² (ii) 5 m²

(i) Force, f = 200 N

Pressure, p =?

Area, a =10

We know,

p = f/a

p = 200/10

p = 20 pa

(ii) Force, f = 200

Pressure, p =?

Area, a = 5

We know,

p = f/a

p = 200/5

p = 40 pa

Define Pressure.

What is the relation between pressure, force and area?

What are fluids? Name two common fluids.

State Archimedes’ principle.
