Question

An object placed on a top of table exerts a force of 100 Newton over an area of 6ms square ,find the pressure exerted ?​

Answer 1

Answer:

Given force = 100n

Given area = 6m square

Therefore pressure exerted= force/ area

= 100n/6m square

= 16.66 P a

Answer 2

Answer:

16. 67 Pa

Explanation:

Force exerted by the object on the table (F) = 100 N

Area of the surface experiencing force (A) = 6 m sq.

We know that, Pressure = Force/ Area

=> 100/ 6

=> 16.67 N/m

= 16. 67 Pa (Ans

NOTE :

Since pressure is directly proportional to force and inversely proportion to area :-

Pressure = Force/ Area

• The greater the area less is the pressure and  the lesser the area more is the pressure.

• The greater the force, the greater is the pressure and, the lesser the force, the lesser is the pressure.

For example :-

A brick resting on a surface exerts a force equal to its weight (mg) on the surface. Now we know that a rectangular brick has a wide surface and thin surfaces on the sides. By changing the orientation of the brick resting on a surface, we are effectively changing the pressure acting on the surface by the same brick.
