B)17 N
C)30 N
D)5.0 N
E)any of the above

For an object to move with constant velocity, the net force acting on it must be zero according to Newton's first law of motion. This means the sum of all forces acting on the object in any direction should cancel out. Since the question does not specify the direction of the given forces, any additional force could potentially balance the existing forces to achieve a net force of zero, assuming the forces are applied in the correct direction to achieve equilibrium.
