Question

Answer 1

Some applications in which we reduce the pressure by increasing the surface area over which the force is exerted are:

Cutting vegetables with blunt knife etc.

Answer 2

Pressure is ratio of force to area. Less the area, more is pressure for same force.

Nail is example of this type. If nail is more pointed it easily penetrate. Because pointed nail has less area hence more pressure.
