The tension in the rope at that point is the force pulling in opposite directions at the point where the rope is being held or attached.
In that case (ignoring the weight of the rope, for simplicity), the tension at any point of the rope will also be 100 N.
The tension at every point in the rope must be 20N, and it must exert 20N of upward vertical force on the top of the bag. If there's any point in the whole arrangement where the upward and downward forces are not exactly equal, then the mass at that point must be accelerating up or down.
A pulling force in a rope is called tension. Tension is the force exerted by a rope when it is pulled taut by two opposing forces.
The reaction force to you pulling on a rope is the tension force exerted by the rope in the opposite direction. This tension force is equal in magnitude and opposite in direction to the force you apply to the rope.
The direction of tension in a rope is away from the object to which the force is being applied. It is a pulling force that stretches the rope and opposes any external forces trying to compress or shorten it.

The tension in the rope will be 100 N, as both forces are pulling on the rope with equal magnitude but in opposite directions. This results in no net force being applied to the rope, maintaining the tension at 100 N.
All rope stretches because it consists of materials at an angle to the load putting tension on the rope, and they try to straighten when pulled. How much the rope can stretch, and at what point the stretch weakens the rope, depends upon the materials used and the rope construction - laid up or braid, and the combinations of these.
Assuming you meant two forces, the tension will be 200N.
To find the tension in rope a in a system of pulleys, you can use the formula T W/(2n), where T is the tension in rope a, W is the weight being lifted, and n is the number of pulleys the rope is passing through.
The tension at every point in the rope must be 20N, and it must exert 20N of upward vertical force on the top of the bag. If there's any point in the whole arrangement where the upward and downward forces are not exactly equal, then the mass at that point must be accelerating up or down.
The tension in the rope is equal to the weight of the hanging block when the block is stationary and not accelerating.
