The weight of the crate is acting downward on the ground and the ground is exerting a force equal to the weight of the crate upward on the crate.
The weight of the crate is acting downward on the ground and the ground is exerting a force equal to the weight of the crate upward on the crate.
Gravity is a force acting down on it. A normal force is acting perpendicular to the ground at the base of the structure.

a girl and a boy are pulling heavy crate at the same time with 10 units of force each . what is the net force acting on ythe object?
You should have friction between the box and the ground, the force you used to push it, the mass of the object, and gravity. The resistance of the air is neglibible. This should be all the forces on an object on flat ground.
All the forces acting on each other are in equilibrium. For instance the restoring force upward from the ground/floor is equal to the strength of the force of gravity, which acts downwards.
For every action there is an equal and opposite reaction, so if you push on a crate, the crate pushes back with a normal force equal to the force exerted. Thus, expect a force of 50 N to push back at you. However, if you meant the normal force of the ground exerted on the box, then that would included the 50 N force and the weight of the crate.
Gravity,contact force, friction, air resistance
If the forces are balanced this means that there is no net force acting
If the crate isn't accelerating ... i.e. sliding at a constant speed, not speeding up or slowing down ...then the forces on it are balanced. The pseudo-force of friction is 140N in the direction opposite toits speed.
An object at rest, or an object with a constant velocity are the two possible states of an object with zero net force. An object with zero acceleration has zero net force. There many be several forces acting on the object, such as the force of gravity and the normal force of the ground. Even though an object sitting on the ground has two forces acting on it (gravity, and the normal force) the object does not accelerate because these forces are equal and opposite. An object with zero net force has all forces acting on it equally balanced and cancelling out
The primary force is gravity.
