Question

4. Find the amount of force if the body has pressure of 178 Pa on 18 mm2​

Answer 1

Answer:

Amount of foce = 3.204 * 10^-8 N.

Explanation:

Given,

Pressure of body(P) = 178 Pa

Area ( A) = 18 mm² = 10^-6 m²

To find: The amount of force

Solution:

Pressure is defined as force(or thrust) per unit area.

i.e P = F /  A

Substituting the values,

178 = F / 1.8*10^-6

or, F = 178 * 1.8 * 10^-6

or, F = 320.4 * 10^-6

or, F = 3.204 * 10^-8 N

Therefore, Amount of foce = 3.204 * 10^-8 N.
