Question

1.
In a bramah press a force of 10 N is applied on a piston of area of cross-
section 5 m2. Then the upward thrust exerted by the piston of area of
cross-section 10 m2 is
1) 2 N
2) 200 N
3) 20 N
4) 100 N​

Answer 1

Answer:

2N

Explanation:

pressure= force/ area

Answer 2

3) 20 N

Explaination:

F1 =10 N

A1 = 5m²

F2 = ?

A2 = 10m²

F1/A1 = F2/A2

10/5 = F2/10

F2 = 10/5 * 10

F2 = 20N
