Question

how does the pressure get affected if the area is doubled keeping the force constant?

Answer 1

pressure is force acting on a certain area
pressure is force/area.so pressure is inversely proportional to area.
if the area is increased the force acting on it will be equally distributed,thus pressure decreases.if the area is decreased,all the force acts in that particular area ,thus increasing the pressure.
i hope this helps u..

Answer 2

if the area is doubled and the force is constant then the pressure will be 1/2 .
pressure=force/area
pressure=force/2 area
pressure=1/2(force/ area)
