Your weight exerts a downward force, while the chair exerts an upward force equal in magnitude to your weight.
C. equal
equal
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.
Reactive force. For every action there is an equal but opposite reaction. So if a box is sitting on the table, and the box weighs one kg, it exerts 9.81N of force on the table. Likewise, the table exerts 9.81N of force on the box in order to keep the box on the table. Otherwise, the box would smash through the table. THESE TWO FORCES ARE EQUAL BUT OPPOSITE, SO THE SUM OF THE TWO WILL ALWAYS BE EQUAL TO ZERO.
They are equal and opposite (Newton's third law).Each action has an equal an opposite reaction. For example: pulling on a rubber band and letting it go will cause it to fly around. This is the action and related response or reaction desired.
Your weight exerts a downward force, while the chair exerts an upward force equal in magnitude to your weight.
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.

When something exerts a force on an object, that object exerts an equal and opposite force on the other object.
Of exactly the same magnitude but in the opposite direction.
Newton's third law of motion explains action and reaction forces. The third law states that for every action force, there is an equal and opposite reaction force. Imagine hitting a Baseball. The bat exerts a force on the ball.
newton's third law
Newton's Law of Motion, the law you stated is specifically his third law.
A force is exerted on a box and an equal and opposite force is exerted by the box is an example that explains Newton's second law of motion. It states that for every action, there is an equal and opposite reaction.
