Can force be two-dimensional?

Yes

Explanation:

Just as motion in two dimensions introduced vectors, forces in two dimensions also involve more involved issues. 

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

explanation:

newton's third law, for every action there is an equal and opposite reaction.
