Question

1 . Calculate the pressure exerted by a force of 200 N is applied on area of 10m². 2. The tip of an all pin has an area (1.0 * 10^-8)m² . find the pressure exerted if force applied is 10 N . 3. An elephant weight 20,000 N stands on one foot of area 1000 cm², how much pressure would it exert on the ground.

Answer 1

We need to state the formula for getting pressure:

Pressure = Force / Area

The units of pressure is given by:

N/m²

In this question we are given:

Force = 200 N

This is the force applied on the surface.

Area = 10 m²

This is the area where the force is concentrated.

Pressure = 200N/10

= 20 N/m²

This is the pressure exerted on the surface.

Answer 2

Answer:

Question :-

1 . Calculate the pressure exerted by a force of 200 N is applied on area of 10m².

Answer :-

$\tt\large\orange{Pressure\: =\:Force\:/ \:Area}$

Pressure = 200 N / 10 m ²

Question :-

2. The tip of an all pin has an area (1.0 * 10^-8)m² . find the pressure exerted if force applied is 10 N .

Answer:-

Force = 10 N

Area = (1.0 * 10^-8)m²

$\tt\large\orange{Pressure\: =\:Force\:/ \:Area}$

Pressure = 10¹ / (1.0 × 10 ^-8)

pressure = 10¹ / 10^-8 = 10^1-8

Pressure = 10^9

Question :-

3. An elephant weight 20,000 N stands on one foot of area 1000 cm², how much pressure would it exert on the ground.

Answer :-

Force = 20,000 N

Area = 1000 cm²

= 1000 / 10,000 = 0.1 m²

$\tt\large\orange{Pressure\: =\:Force\:/ \:Area}$

= 20,000 / 0.1

= 2, 00,000 Pa = 2 x 10^5
