Question

a cubical steel block of side 5 cm exerts a pressure of 4000 Pascal when placed on a plane calculate the mass of the block

Answer 1

From the given condition, we can get  the cubical steel block of side 5 cm. It exerts the pressure of 4000 Pascal.

Then we need to calculate the mass of this black. It is important to know that 4000p=mg/0.05m.

We also know that force=weight which is 200=10m. So the value of m is 20kg.

Answer 2

Answer:

1kg

Explanation:

Pressure= Force ÷ Area

4000pa = Force ÷ 0.05²m

Force = 10N

Weight(Force) = m × g

10N = m × 10

m = 10÷10

m = 1kg
