When a heavy desk is not moving, the main forces acting on it are the gravitational force pulling it downward and the normal force pushing back up from the ground to support its weight. These two forces are in equilibrium, which is why the desk remains stationary.
The reaction force to the gravitational force acting on your body as you sit in your desk chair is the normal force exerted by the chair on your body. It is equal in magnitude and opposite in direction to the force of gravity, balancing the forces and keeping you in equilibrium.
forces acting on the book when it rests in your hands are: gravity, the equal and opposite force exerted by your hand on the book (in opposition to force of gravity). Also, air pressure, but its from all sides so it cancels itself out.
When a ball moving hits a ball that is at rest and a human pulling out a book from a desk.
The normal force acting on a book sitting on a desk is equal in magnitude and opposite in direction to the force of gravity pulling the book downward. This force prevents the book from falling through the desk and is what keeps the book in place.
The desk will experience a force in the direction of the push from the two people, causing it to move in that same direction as long as the force applied is greater than any opposing forces like friction.

The forces acting on the bookends will be balanced when the gravitational force acting downward on the books is counteracted by the normal force acting upward from the desk through the bookends. This equilibrium allows the row of books to remain standing up without falling over.
The reaction force to the gravitational force acting on your body as you sit in your desk chair is the normal force exerted by the chair on your body. It is equal in magnitude and opposite in direction to the force of gravity, balancing the forces and keeping you in equilibrium.

Some actions while sitting at a desk include applying force to the keyboard, mouse, or desk surface. Reaction forces are generated against the body due to the chair supporting your weight, and the desk resisting movements like pushing or leaning. Additionally, muscles may contract to maintain posture, creating internal forces within the body.
No, if the force exerted in one direction is greater than the force exerted in the opposite direction, the desk will move in the direction with the greater force, in this case to the left. The desk will move in the direction of the net force acting on it, which is the difference between the two forces (15 N to the left - 10 N to the right = 5 N to the left).
When two completely equal forces are applied at one object or each other from opposite angeles. When this happens the object to which force is applied will not move because the two forces will cancle each other out.In other words, if I push a desk left at 2n and somebody else pushes a desk right at 2n the desk will not move.
