Question

Hydraulic press works on Pascal's law. If input piston area is 5 cm² and output is 100 cm², and input force is 20 N, output force is:
  1. A
    400 N
    Correct
  2. B
    1 N
  3. C
    2000 N
  4. D
    4 N

Correct answer

400 N

Explanation

P₁ = P₂ → F₁/A₁ = F₂/A₂. F₂ = 20 × 100/5 = 400 N.
