A 30 N crate is submerged in water. The amount of buoyant force acting on the crate is 25 N. What will the crate do?

The crate will float and accelerate upwards. The only force acting on the crate is the buoyant force, and it acts upwards on the crate.
The crate will sink and accelerate downwards. The only force acting on the crate is the buoyant force, and it acts downwards on the crate.
The crate will sink and accelerate downwards. The buoyant force acting upwards on the crate is smaller than the downward force of gravity on the crate.
The crate will sink and accelerate downwards. The buoyant force and the gravitational force are both acting downwards on the crate, making it accelerate down.
is it the first one?

  1. the forces acting on the crate are gravity and buoyancy

    what's the net result?

  2. The answer is "The crate will sink and accelerate downwards. The buoyant force acting upwards on the crate is smaller than the downward force of gravity on the crate."

  3. Grace is correct, it's "The crate will sink and accelerate downwards. The buoyant force acting upwards on the crate is smaller than the downward force of gravity on the crate"
