b) Force and area both are tripled?
c) Area is doubled while keeping the force constant?
Explain with proper reason and I will mark you the brainliest

Answer 1

Answer:

1. The pressure gets doubled.

2. The pressure remains same.

3. The pressure reduced to half.

Explanation:

Let P be original pressure and p be resulting pressure.

1. P= F/A

p = 2F/2

p = 2 (P)

2. P= F/A

p= 3F/3A

p= F/A [3 in both numerator and denominator gets cancelled]

p= P

3. P= F/A

p= F/ 2A

p= 1/2 (P)
