Question

32. A small cylinder of 2 cm diameter is connected to a large cylinder of 20 cm diameter
and each cylinder is fitted with suitable pistons. An incompressible fluid is filled in
the cylinder. If a force of 60 N is applied to the piston of the small cylinder, then the
force exerted on the piston of the large cylinder will be
(A) 12,000 N (B) 6,000 N (C) 1,200 N
600 N​

Answer 1

Answer:

600N

Explanation:

60/2 ×20

= 60×10

600N

Answer 2

Answer:

Solution:

According to Pascal's law, pressure of a fluid is transmitted equal in all directions. Hence

Fi F2 = A1 A2 or F₂ =() F 2 XA2

F2 = 60 7x(0.02) X π X (0.2) 2

= 6000N
