Answered by aliasgar53

side with 30 N force because it will exert more pressure of 150 Pascal.

sania95: in detail i want

aliasgar53: oh wait

aliasgar53: : pressure=force/ area

aliasgar53: for stack 1:

aliasgar53: pressure =20/2=10Pa

aliasgar53: for stack2:pressure=30/0.2=150Pa

aliasgar53: second stack will exert more pressure on ground and willl go ddown and hence the first stack will goo up.

aliasgar53: ok bye
