Question

What is the weight of an object that has a base which is 3 square metre and which exerts a pressure of 21 Pascal?

Answer 1

Answer:

63 N or, 6.42 kgf.

Explanation:

Given,

Area = 3 m²

Pressure = 21 Pa

Weight = Pressure = Force/Area

Let the force be denoted as x.

= 21 = x/3

= 63 N = x

N to kgf = 1 kgf = 9.8 N

= 63 N = (63/9.8) kgf

= 6.42 kgf

Hope this helps.
