Answer:
166.6 N
Explanation:
Given that,
Force, F₁ = 20 N
Area, A₁ = 10 dm² = 1000 cm²
We need to find the new force if the area of the larger piston is 120 cm². According to Pascal's law,
[tex]F_1A_1=F_2A_2\\\\F_2=\dfrac{F_1A_1}{A_2}\\\\F_2=\dfrac{20\times 1000}{120}\\\\F_2=166.7\ N[/tex]
So, the force on the larger piston is equal to 166.7 N.
