Answer:
The force applied on the big piston is 1306.67 N
Explanation:
Given;
force applied on small piston, F₁ = 200 N
diameter of the small piston, d₁ = 4.37 cm
radius of the small piston, r₁ = d₁/2 = 2.185 cm
Area of the small piston, A₁ = πr₁² = π(2.185 cm)² = 15 cm²
Area of the big piston, A₂ = 98 cm²
The pressure of the piston is given by;
Where;
F₂ is the force on big piston
Therefore, the force applied on the big piston is 1306.67 N

Answer:
The thickness of the oil film is 198 nm.
Explanation:
Given that,
Refractive index of glass plate = 1.60
Refractive index of oil = 1.29
Wavelength = 511 nm
We need to calculate the thickness of the oil film
Using formula of path difference
Where, n = refractive index
t = thickness
= wavelength
Put the value into the formula
Hence, The thickness of the oil film is 198 nm.
