In a hydraulic lift, if the radius of the smaller piston is 5 cm, and the radius of the larger piston is 50 cm, then the weight that the larger piston can support when a force of 250 N is applied to the smaller piston is

  1. A 50 kN
  2. B 100 kN
  3. C 40 kN
  4. D 25 kN
Verified Solution

Answer & Solution

Correct Answer

(D) 25 kN

Step-by-step Solution

Detailed explanation

\(F_2 = F_1 \left(\frac{r_2}{r_1}\right)^2\) \(F_2 = 250 \text{ N} \left(\frac{50 \text{ cm}}{5 \text{ cm}}\right)^2 = 250 \text{ N} (10)^2\) \(F_2 = 25000 \text{ N} = 25 \text{ kN}\)
