Question

26. Pressure on an object of area 20
cm^2 being acted upon by a force
of 100 N is

1/5 N/cm^2
2000 N cm^2
1/2000 N cm^2
5 N/cm^2
​

Answer 1

Understanding the question: This question says that we have to find out the pressure if the area of an object is 20 centimetres sq. and a force of 100 Newton have being acted upon it!

Provided that:

• Force = 100 N
• Area = 20 cm sq.

To calculate:

• Pressure

Solution:

• Pressure = 5 N/cm²

Using concept:

• Pressure formula

Using formula:

• ${\small{\underline{\boxed{\sf{Pressure \: = \dfrac{Force}{Area}}}}}}$

Required solution:

$:\implies \sf Pressure \: = \dfrac{Force}{Area} \\ \\ :\implies \sf Pressure \: = \dfrac{100}{20} \\ \\ :\implies \sf Pressure \: = \dfrac{10}{2} \\ \\ :\implies \sf Pressure \: = 5 \: N/cm^2$

The pressure is equal to 5 N/cm^2 Therefore, option D is correct!
