The area of cross-section of the two vertical arms of a hydraulic press are 1 `cm ^(2)` and `10 cm^(2)` respectively. A force of 10N applied. As shown in the figure, to a tight fitting light piston in the thinner arm balances a force F applied to the corresponding piston in the thicker arm. Assuming that the levels of water in both the arms are the same, we can conclude:-

A

F=100N

B

F=50N

C

F=25N

D

F, as applied, cannot balance the effect of the force on the first piston

Text Solution

Verified by Experts

The correct Answer is:
B
`(10xx cos 60^(@))/(1)=(F)/(10)rArrF=50N`
