Question

A force of 250 Newton's is applied on an object of an area of 200cm square

Answer 1

Answer:

20 N

We know that, Pressure=

Area

Force

⇒Pressure=

10

2

=0.2Ncm

−2

Now, Pressure=0.2

Again, Force=Pressure×Area

Force=0.2×100=20N

Answer 2

Answer:

Explanation:

Basic concepts :

Force is push or pull that causes an Acceleration in a body. Basically Force is the cause of change of state. Force exerted on unit area, is the Pressure exerted on the body.

Solution :

In the given question,

Force applied = 100 N

Area of the object = 2m²

Both are in S. I. Units. So need to convert into any other system.

Pressure exerted by a force on a object of Area is given by,

Therefore,

A force of 100N is applied to an object of area 2m square. The pressure is 50 Pa.
