Sample AP Physics 1 practice question

A small object of mass m and volume V is released from rest at the bottom of a tank filled with a fluid of density ρ. The density of the object is less than ρ, and drag forces are negligible. Which expression gives the magnitude of the object's initial upward acceleration?

g(ρV/m - 1)

Correct answer

g(1 - ρV/m)

g(ρV/m + 1)

g(m/ρV - 1)

Explanation

Applying Newton's second law with buoyant and gravitational forces.
