In a vehicles lifter, the enclosed gas exerts a force \(F\) on a small piston of \(8 \mathrm{~cm}\) diameter.
The pressure is transmitted to a second piston of diameter \(24 \mathrm{~cm}\). If the mass of the vehicle to be lifted is \(1400 \mathrm{~kg}\), then \(F\) must at least be \(\left(g=10 \mathrm{~ms}^{-2}\right)\)
- A \(1600 \mathrm{~N}\)
- B \(1200 \mathrm{~N}\)
- C \(1800 \mathrm{~N}\)
- D \(700 \mathrm{~N}\)
Answer & Solution
Correct Answer
(A) \(1600 \mathrm{~N}\)
Step-by-step Solution
Detailed explanation
Given, force on small piston, \(F_1=F\) Diameter of small piston, \(d_1=8 \mathrm{~cm}\) Mass of vehicle placed on large piston (lift), \[ M=1400 \mathrm{~kg} \] Diameter of large piston, \(d_2=24 \mathrm{~cm}\) By using Pascal's law, Equal pressure will be transmitted from…
