Question

A hammer exerts a force of 1.5 N on a nail. If area of cross section of nail is 3

,

then find the pressure exerted on it.​

Answer 1

Answer:

0.5 Pascal

Explanation:

Given that: Force exerted by hammer is 1.5 N.

Area of cross section on which the force applied is 3 units square.

Need to find: Pressure exerted on it.

Concept : Formula for finding pressure is

P = F/A

Where,

• P denotes pressure exerted
• F denotes force applied
• A denotes area on which force is applied

Solution:

Finding Pressure exerted :-

P = F/A

P = 1.5/3

P = 15/30

P = 1/2

P = 0.5 Pascal

___________________

• Henceforth, pressure exerted on the cross section by hammer is 0.5 Pa.

Answer 2

Answer:

50 Pascal

Explanation:

Force = 1.5 N

Area = 3cm = 0.03 m    (Converted cm to metre)

Pressure = Force/Area

= 1.5/0.03 = 150/3             (Added decimal points)

= 50 Pascal
