Initial data: Pw (weight of the considered part in air) = 10 N; Fа (buoyancy force that acts on the part in oil) = 2 N.
The weight of the part in question in engine oil will be equal to the difference between its weight in air and the buoyancy force: Рм = Рв – Fa.
Calculation: Рm = 10 – 2 = 8 N.
Answer: The weight of the part in question in engine oil is 8 N.
