what will be the net force on the object?will the object move?to what direction will it move?
The net force on the crate is 70 N to the left while it's moving to the left, and 20 N to the right while it's moving to the right. If the 100N force and the 50N force are acting on it at the same time, then the net force on the crate is 20 N towards the left.
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.
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.
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.

crate- direct object
The net force on the crate is 70 N to the left while it's moving to the left, and 20 N to the right while it's moving to the right. If the 100N force and the 50N force are acting on it at the same time, then the net force on the crate is 20 N towards the left.
The direction of friction on the crate is opposite to the direction in which it is sliding. In this case, since you are pushing the crate to the right, the friction will act to the left in order to oppose the motion.

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?
