The question seems to be incomplete. Here is the complete question:

In a hydraulic jack as shown mass of the car W =800 kg, A₁ 10 cm² A₂ = 10m². The minimum force required to lift the car is:

A) 1 N

B) 0.8N

C) 8N

D) 16N

Solution:

The answer to this question is B) 0.8N

F₁/A₁ = F₂/A₂

F/10 = 8000/ 10 x 10⁴

= F = 0.8 N
