Question

A wooden piece 5n in weight and 5cm*3cm*2cm in size lies on 5cm*2cm face . The pressure exerted by it in n per cm^2

Answer 1

Let

F=5n

area cover =5×2=10cm=0.1m

pressure=F/A

=5/0.1=50

Answer 2

Answer:

the  answer is 0.5

Explanation:

pressure formula is P=F/A

so P= 5N/5cm* 2cm

=P=5N/5*2

=P=5N/10cm

P=5/10

P=1/2

as pressure is in fraction it is converted into decimal

there fore 0.5 is the answer
