Answer:
(A) 50 Pascals
Explanation:
Given :
To find :
Pressure = Force / area
Pressure = 5 N/ 0.1 m²
Pressure = 50/1
Pressure = 50 N/m²
1 N/m² = 1 Pascal
Pressure = 50 pascals
The pressure acting on the surface area of 0.1 m² with a force of 5 Newtons is equal to 50 Pascals
Hence option (a) is correct
Note : pressure can be measured in N/m², N/cm², N/mm²
Given :-
To Find:-
Solution :-
➦Pressure = Force/Area
➭ P = F/A
➭ P = 5/0.1
➭ P = 50/1
➭ P = 50 Pascal
∴ The pressure acting on the surface is 50Pa.
Hence, option (a) 50N/m² is the correct answer.
