About 20kg of force.
how much force is needed to hold the 2kg object
Hold on there. Mass doesn't control the force. Force controls the acceleration. As the mass of an object decreases, less force is required to produce the same acceleration. If the accelerating force is gravitational, that force will decrease. If it is not, then the force will not decrease.
Normal Force from your hands on the 1 kg object. Gravity is being acted on the 1 kg object.
Lift any object. Grav. force is acting down, you must apply an upward force to lift the object. Work is force applied through a distance, so work is done if you lift it, but not if you hold it still.
About 20kg of force.
how much force is needed to hold the 2kg object
The force of your hands holding on two sides of the object you wish to hold. Although the gravitational force that is pulling the object downward is great; the force your hands are pressing onto the sides of the object is a lot greater. You will find that if you don't hold an object as tightly (decrease the force) it may drop. This is because the gravitational force increases.

you mean will it not squish under load? I would say so, it takes alot of force to squash a can (about 20kg+) and Im sure a block like this weighs alot less.
The load force is applying a force to move or hold an object that has weight.

You are measuring the magnitude of the force required to hold the object stationary within a particular gravitation field. The weight of an object is relative to the gravitational field acting upon it. Mass is a physical property of an object where weight indicates a force acting against the object. The weight of an object on the moon will be about 1/6th of the weight it has on Earth, but its mass will be the same in both places.
According to Newton, it accelerates (Force = mass x acceleration). But beware, the force is the net (total) force, not just what you apply. For example when you hold a heavy object you are supplying a considerable force. But gravity is pulling in the opposite direction so the total force is zero. Similarly, if you try to slide a heavy object along a road, if you cannot overcome the limiting frictional force, nothing will happen.
The force required to hold a 12 kg box off the ground would be equal to the weight of the box, which is calculated by multiplying the mass by the acceleration due to gravity (9.8 m/s^2). Therefore, the force required would be approximately 117.6 newtons.
Press and hold X when targeting an object that is possible to use the force on. If you have a blue lightsaber, an object that you can force will have a glowing ring of blue around it. This is the same for all loghtsaber colors. Hope this helps!
