Question

A pressure of 49 Newton metre square acts on a body having a contact area of 2.5 metre square find the force applied on the body

Answer 1

Correct question:

A pressure of 49 Newton per metre square acts on a body having a contact area of 2.5 metre square find the force applied on the body

Given:

Pressure = 49 Pa.

Area = 2.5 m².

To find:

The force applied on the body.

Solution:

Pressure = 49 Pa.

Area = 2.5 m².

Force = ?

We know that,

$Pressure = \dfrac{Force}{Area}\\ \\or, \dfrac{Force}{Area} = Pressure$

⇒Force = (Pressure ×Area)

             = (49×2.5)

            = 122.5 N.

∴ 122.5 N force is applied on the body.

Answer:

            122.5 N force is applied on the body.
