A hydraulic press has a large circular piston of radius 0.8m and a circular plunger of radius 0.2m. A force of 500N is exerted by the plunger. Find the force exerted on the piston
A
8000N
B
4000N
C
2000N
D
31N
correct option: d
Pressure on piston = pressure on the plunger
(\frac{520}{\pi\ \times\ 0.8 \times\ 0.8}) = (\frac{F}{\pi\ \times\ 0.2 \times\ 0.2})
F = 31N
