Question

. How do you increase the pressure by
keeping
(a) area unchanged and
(b) force unchanged?

SCERT Class 8 Telangana, Physical Science Chapter 1 Force

Answer 1

a. by increasing force and keeping area unchanged we can increase pressure

b. by decreasing area and keeping force unchanged we can increase pressure

hope this helped :) :)
if it did plz mark as brainiest :)

Answer 2

Pressure is directly proportional to Force and inversely proportional to Area.

So, To increase pressure

(a)By keeping area unchanged,  we have to apply more Force to apply more pressure.

(b)By keeping Force unchanged, we have to decrease the area to increase pressure.
