Answer:
2× 10⁴ cm²
Explanation:
By Pascal's law, the pressure increased using
one piston is communicated everywhere in the
fluid. Thus, the same pressure acts on the other
piston.
Cross-sectional area of piston 1 is A₁
100 cm²
=
0.01 m²
=
Force on piston 1 is F₁ = 107 dyne = 100 N
Force on piston 2 is F₂ = 2000 kg wt
102 x 104 N
=
2000 ×
Let the cross-sectional area of Piston 2 be A2
A
By Pascal's law, P₁ = P₂ ⇒
F₁
A₁
F2
A2
=
F2A1
F₁
2 x 104 x 0.01
100
⇒ A=
= 2 m² = 2 x 104 cm²
