No force is necessary to maintain constant speed.
A balanced group of forces is equivalent to no force.
An unbalanced group of forces is equivalent to someforce,
which is capable of changing the speed of something.
To maintain a constant velocity, the force needed to overcome the frictional force must be equal in magnitude but in the opposite direction. Therefore, a force of 10N is needed to maintain the constant velocity of the sliding object.
Newton's 1st Law of Motion states that an object will maintain its speed when there is no net force acting on it. The question refers to free space and constant velocity -- the net force has to be zero. =========================
An unbalanced force is a force that causes an object to change its motion by speeding up, slowing down, or changing direction. A balanced force is when two forces acting on an object are equal in size but opposite in direction, causing the object to stay at rest or move at a constant speed.
The total value of the frictional forces acting on the bike and its rider would be 400 N, which is equal in magnitude to the pedal force applied. This is necessary to balance the pedal force and maintain a constant speed when the bicycle is moving at a constant velocity.
If the chair is moving at a constant velocity, the force of friction is equal and opposite to the force you are exerting on the chair. This is to maintain the equilibrium of forces acting on the chair.
To maintain a constant velocity, the force needed to overcome the frictional force must be equal in magnitude but in the opposite direction. Therefore, a force of 10N is needed to maintain the constant velocity of the sliding object.

It will cause acceleration in the direction of the net force.

It could be called superfluous. No force is necessary to maintain motion.
Is a monkey bar a unbalance force
An object maintains a constant velocity when the net force acting upon that object is zero. Therefore, a force pushing against the object that exactly opposes the force(s) due to friction (in both magnitude and direction) will result in a net force of zero, and the object will maintain a constant speed.
An unbalanced force is a force that causes an object to change its motion by speeding up, slowing down, or changing direction. A balanced force is when two forces acting on an object are equal in size but opposite in direction, causing the object to stay at rest or move at a constant speed.

Maintain a constant speed
The total value of the frictional forces acting on the bike and its rider would be 400 N, which is equal in magnitude to the pedal force applied. This is necessary to balance the pedal force and maintain a constant speed when the bicycle is moving at a constant velocity.
