Question

how will the force change when
1.force is halved
2.area is made one fourth

Answer 1

1) if force is halved , then Fg will also be half.
2) if area is made 1/4, then Fg will increase 4 times....as it is indirectly proportional to Fg.


Fg(force of gravitational)

Answer 2

A correction in your question :-
" how will the Pressure change when
1.force is halved
2.area is made one fourth

First of all, Pressure = Force/ Area..
Pressure is directly proportional to Force and inversely proportional to Area

1) Force is halved.
Here Force is halved, Area is constant. So Pressure also gets halved.

2) Area is made one fourth
Here Area is decreased. So absolutely Pressure should increase. So P 1= F / A at initial. now P2 = F/A/4 =4 F/A=4 P1
So final pressure is four times.

Hence pressure becomes four times
