Question

A prefabricated slab of 50 N lie on the ground with its sides of dimensions 20cm x 10 cm. What will be the pressure exerted on the ground by the slab?

Answer 1

Answer:

2.5×10^+5 Pa will be the pressure on the ground by slab.✓

Answer 2

Answer :

• Pressure exerted on the ground by the slab will be 2500 Pa.

Step-by-step explanation :

GivEn :

• Dimensions of the ground are 20 cm × 10cm .

• A prefabricated slab applies force of 50 N on the ground .

To find :

• Pressure exerted by the slab on the ground = ?

SoluTion :

As we are given with the dimensions of the ground and force applied , let's convert the dimensions, i. e.,

• 20 cm = 0.2 m

• 10cm = 0.1 m

⇛ Area of the ground = Length × Breadth

⇛ Area of the ground = 0.2 × 0.1

⇛ Area of the ground = 0.02 m²

Now,

By using the formula to calculate the pressure exerted,

⇛ Pressure exerted = Force / Area

⇛ Pressure exerted = 50/0.02

⇛ Pressure exerted = 2500 Pa

Hence, Pressure exerted on the ground by the slab will be 2500 Pa.
