The size of a reaction force is equal in magnitude but opposite in direction to the action force. This is based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
The force exerted by Earth's gravity on a car is equal in size (magnitude) to the force the car exerts on Earth. This is described by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
The force pulling down is typically equal in size to the net force pushing up on an object in equilibrium. This is known as Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
The idea of a reaction force comes from Newton's third law; "If object A exerts a force on object B ,then object B will exert an equal but opposite force back on A". In many problems some of the forces are considered as the "initiating" force or the applied force. When you consider a force as being applied, like a bulldoser pushing a rock, then the force which must act back , the rock pushing back on the doser, is called the reaction force. Sometimes you don't really have an initiating force but it still convienient to think of one force as the force of interest and the back force as the reaction force. There is no single formula for reaction force since it can apply to any force. For example, the earth attracts you with a force mg (your weight), then you can think of the reaction force as you attract the earth with a force -mg; equal but opposite.
The name often given to the force exerted by the first object on a second object is the action force.
A reaction is not a separate force; it is a force that occurs as a response to an action. In the context of contact forces, a reaction force is the force exerted by an object in response to a force acting on it. It is a contact force that arises due to the physical interaction between two objects.

All Forces! For every action there is an equal and opposite reaction."The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs"

It is in a state of dynamic equilibrium. The outwards force from the nuclear reaction in the core is balanced by the inward force of gravity. In fact as with many dynamic equilibria any star like the sun oscillates in size.
"action/reaction" does not mean " force". "Applying force" is an action, not the force itself. So, applying force will create a reaction, which may or may not balance the applied force.

Always centrifugal is the reaction force for centripetal
Reaction Force.
a reaction force
A reaction is not a separate force; it is a force that occurs as a response to an action. In the context of contact forces, a reaction force is the force exerted by an object in response to a force acting on it. It is a contact force that arises due to the physical interaction between two objects.
The force acting on an object "A" from outside is action force , and the reaction force is the force exerted by A to the outside object . Therefore, it is obvious that action force and the corresponding reaction force cannot act on one and the same body.
