Question

how would pressure change if (a) area is tripled keeping force constant (b) force is tripled keeping area constant

please send it's urgent!​

Answer 1

We know that, Pressure = Force Applied / Area of contact

(a) If Area is tripled then,

Pressure' = Force / 3 × Area

=> Pressure' = 1/3 × Force / Area

=> Pressure' = 1/3 × Pressure

Therefore, new pressure would be equal to one third of the original pressure

(b) If force applied is tripled then,

Pressure = 3×Force / Area

Pressure' = 3 × Pressure

Therefore, new pressure would be equal to three times the original pressure.

Hope this helps!!
