Question

why is a person laying on a single nail is hurt more than the same person to lying on bed of nails ?​

Answer 1

Because single nail have very minute surface

But nail bed have large surface area

And we know that pressure is inversely proportional to area

so less area more pressure and it will hurt the person

Answer 2

Answer:

Coz larger the surface area less is the pressure exerted and smaller the surface area more is the pressure exerted....
