Answer 1

a) answer is vertical

d ) area in contact = 0.02m^2

force = 30 N

$pressure = force \div \: area$

= 30/0.02

=1500 pascal

Answer 2

Answer:

1) Its vertical. because there is a rule which says, pressure is inversely proportional to surface area, which means if pressure is more, surface area is less and vice versa. So in the given picture, only vertical one, has the less surface area in contact to powdered lime, so it applies greatest pressure among all three.

2) area in contact = 0.02m^2

force = 30 N

pressure = force \div \: areapressure=force÷area

= 30/0.02

=1500 pascal
