a hammer exerts a force of 1. 5 Newton on each of the two nails A and B. The area of cross section of tip of nail A is 2mm square while that of nail B is 6 millimetre square .Calculate the pressure on each nail in Pascal.

p=f/a.
In case :1
force=1.5N
area=2mm square=2/1000000m square
so, pressure=1.5/2/1000000=1500000/2
=750000pa
Case:2
f=1.5N
area=6mm square=6/1000000m square
so, pressure= f/a
=1.5/6/1000000
=1500000/6=250000pa.

F=1.5 N
Mass of A=2 mm²=0.000002 m²
Mass of B=6 mm²=0.000006 m²
Pressure on A=Force/Area of A=1.5/0.000002=7,50,000 Pa=7.5×10^5 Pa
Pressure on B=Force/Area of B=1.5/0.000006=2,50,000 Pa=2.5×10^5 Pa
I hope it help you....
