IN CASE OF A NAIL
F = 1.5 N
A =2MM2 =2/ 1000000 M2
P =F/A = 7.5 X 105PA
IN CASE OF B
A = 6MM2= 6/1000000 M2
F = 1.5 N
P =F/A = 2.5 X 105 PA
F = 1.5 N
A =2MM2 =2/ 1000000 M2
P =F/A = 7.5 X 105PA
IN CASE OF B
A = 6MM2= 6/1000000 M2
F = 1.5 N
P =F/A = 2.5 X 105 PA

P= F/A
= 1.5/2× 10^-6
= 7.5×10^5
= 1.5/2× 10^-6
= 7.5×10^5
