Question

If pressure exerted by the following cube is 200Pa, find the amount of force it projects down. Also calculate the new Pressure if its side is doubled to 20cm while keeping force constant

Answer 1

Answer:

1st case

p=200pa1

a=10cm=10-⁴m

P =F/A

F=200×10-4

2nd case

F=200×10-4N

A=20×10-4

P=F/A

P=200×10-⁴/20×10-4

P=10pa
