Question

when we hit a person with bundle of paper whose weight is 50g and a iron scale 50g on hitting with paper there will be less pain and by hitting with scale there will be more pain proove it
​

Answer 1

Answer:

Explanation:

let paper area = A

let iron scale area = a

here force of both objects are same = f

but surface area of paper more than surface area of iron scale

A>a

pressure1 = pressure2

f/m^2= f/m^2

f/A<f/a

thus iron scale has more pressure impact thus causing more pain

hence proved
