Buoyant Force in an Accelerating Frame
A cube of side length L and density ρ_cube is suspended by a string while fully submerged in a fluid of density ρ_fluid, where ρ_cube > ρ_fluid. The system is in an elevator accelerating upward with magnitude a. What is the change in the string’s tension compared to its value when the elevator is at rest?
A
Increases by ρ_cube·L³a
B
Remains the same
C
Decreases by ρ_fluid·L³a
D
Increases by (ρ_cube - ρ_fluid)L³a
