Question

How will the pressure vary if area is doubled while keeping the force constant?​

Answer 1

When the surface area is doubled, keeping the force constant, the pressure will decrease.

please mark me as brainliest.

Answer 2

Hello....

Given:

Area of contact is doubled keeping the pressure constant.

To find:

Change in pressure.

Calculation:

Pressure is a scalar quantity calculated by the ratio of the trust (or force ) and the surface area upon which the force acts.

Initially ;

Therefore,P=F/area

Finally ;

Finally ;

Therefore P2=F/2×(area)

Dividing the two equations :

Therefore;P2/P=1/2

=P2=1/2×P

=Final pressure=1/2×(initial pressure)

So, final answer is :

Final pressure becomes half of initial pressure when the area of contact is doubled.
