The balanced force is required to be acting on the window washer to keep it in the same position.
The external effort causing the change in the state of motion of any object is known as force.
Forces are generally of two types namely balanced force and unbalanced force.
When an object is applied with more than one force, such that net force on the object is zero and due to this the state of motion of object remains unaffected, then such type of force is called balanced force.
Similarly, the forces on the object having some net magnitude and causing some motion to the object are known as unbalanced forces.
So as per the given problem, for keeping the window washer in the same position, it is required to apply with a balanced force.
Thus, we can conclude that balanced force is required to be acting on the window washer to keep it in the same position.
