Answer 1

Given that:

The area of the bottom of a tiffin box is 0.30 sq. m.

And weight is 60 N.

To Calculate:

The pressure exerted by the box on the shelf in N/sq. m.

We know that:

Pressure = Force / Area

Finding the pressure exerted:

↠ Pressure = 60/0.30

↠ Pressure = (60 × 100)/30

↠ Pressure = 200

Hence,

The pressure exerted by the box on the shelf is 200 N/sq. m.
