Question

A solid body weighs 234N. When placed on a wooden plank, the area of contact is found to be 10 squre meter. Find the pressure exerted
by the brick on the ground?​

Answer 1

Answer: weight of body = 234N

area of contact = 10 m²

since the units are all in SI , there is no need to convert them.

pressure =  force×area

here , the force is equal to the weight.

pressure = 234× 10

             = 2340 m²

hence , the pressure exerted by the object on the plank is 234 N/m².

Explanation:

Answer 2

Answer:

Given :-

• A solid body weighs 234 N.
• When it placed on a wooden plank, the area of contact is found to be 10 m².

To Find :-

• What is the pressure exerted by the brick on the ground.

Formula Used :-

$\clubsuit$ Pressure Formula :-

$\bigstar \: \: \: \: \sf\boxed{\bold{\pink{Pressure =\: \dfrac{Force}{Area}}}}\: \: \: \: \bigstar$

Solution :-

Given :

• Force = 234 N
• Area of Contact = 10 m²

According to the question by using the formula we get,

$\implies \sf\bold{\purple{Pressure =\: \dfrac{Force}{Area}}}$

$\implies \sf Pressure =\: \dfrac{\cancel{234}}{\cancel{10}}$

$\implies \sf Pressure =\: \dfrac{\cancel{117}}{\cancel{5}}$

$\implies \sf\bold{\red{Pressure =\: 23.4\: Pa}}$

$\therefore$ The pressure exerted by the brick on the ground is 23.4 Pa .
