Question

IF THE MAGNITUDE OF FORCE ACTING ON A SURFACE IS DOUBLED AND THE AREA ON WHICH IT IS ACTING IS HALVED, THEN WHAT WILL BE THE EFFECT ON PRESSURE????


PLEASE HELP REALLY NEED IT

Answer 1

Answer:

The pressure will become 4 times.

Explanation:

We know that

Pressure (P) =force / area

Let the new pressure be P'

Now,

By problem,

F'=2F

A'=A/2

So,

P'= F'/A'

=2F/A/2

=2×2 F/A

=4 P (ans)

Answer 2

Answer:

pressure become 4 times the original

Explanation:

p = f / a

p = 2f / a/2

p = 2× 2f /a = 4 (f/a) = 4P
