Question

A hammer exerts a force of 1·5 N on each of the two nails A and B. The area of cross section of tip of nail A is 2 mm^2 while that of nail B is 6 mm^2. Calculate pressure on each nail in pascal.​

Answer 1

Solution :-

Nail A :-

Force ( F ) = 1.5 N

Area ( A ) = 2 mm² = 2 x 10 ^ - 6 m²

Pressure ( Pa ) = F/A

= 1.5 /(2 x 10^-6)

= 7.5 x 105 Pascal

Nail B :-

Force ( F ) = 1.5 N

Area ( A ) = 6 mm² = 6 x 10 ^ - 6 m²

Pressure ( Pa ) = F/A

= 1.5 / (6 x 10^-6)

= 2.5 x 105 Pascal
