The answer is gravity, a force that pulls objects down.
The action force when you sit down on a chair is the force exerted by you on the chair. This force is equal in magnitude and opposite in direction to the reaction force exerted by the chair on you, which supports your weight and keeps you from falling through the chair.
The upward force exerted by a chair when you sit on it depends on your weight and the design of the chair. The force is equal to the force of gravity acting on you, to keep you balanced and prevent you from falling.
When you sit on a chair, the resultant force on you is your weight acting downward, countered by the normal force exerted by the chair on you. These two forces are equal in magnitude but opposite in direction, creating a balanced force system that allows you to remain stationary on the chair.
When you sit in a chair, the action force is the downward force you exert on the chair due to your weight. The reaction force is the upward force exerted by the chair on you, supporting your weight and keeping you from falling to the ground.
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.

Yes, it is true that the net force acting on you when you sit still in a chair is zero. This is because the force due to gravity pulling you downwards is balanced by the normal force exerted by the chair pushing you upwards, resulting in no acceleration in any direction.
The Answer is (A) - Zero Explanation: When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces.
If your feet are off of the floor, then the chair exerts your total weight against you.
When a person sits in a chair, the main forces acting on them are the gravitational force pulling them downward towards the Earth and the normal force exerted by the chair pushing them upward to counteract gravity. Frictional forces between the person and the chair also play a role in keeping them seated comfortably.
Assuming that the seat of the chair is horizontal, and you an penis d the chair are stationary, the key forces here are your weight, which is acting vertically downwards on to the chair, and an equal reaction force, or normal contact force, of the chair acting on you. This force acts vertically upwards. You could also include the forces of the air acting on you and vice versa, but this is probably not what you're after.
A normal force.
The chair is pushing up with a force equal to your weight.
