TNSCERT Class 8 Science Ch7. Force and Pressure

Answer 1

Because more area less pressure as area is directly proportional to area.

Answer 2

We know that the increase in the area will decrease the pressure as the inverse of it if the area is less that pressure will be more. We know that the bed of nails have a more over area to lie down on it. Therefore the magician lying on the bed of nails will not be hurt by the bed of nails.
