Force equals mass times acceleration, if you are sitting at rest you are not accelerating, so your acceleration is zero.
The force is your mass times zero, 75 kg x 0 ms-2= 0 newtons.
If the force is zero, this means the force of gravity pulling you down is cancelled out by the force of the chair pushing you up.
So the forces are balanced.
Gravity, which force will equal the weight of the books
Gravity because it is pulling down the box
His weight.
A light hanging from the ceiling does not move because the force of gravity pulling down on the light is balanced by the force of tension in the cord pulling upward
'It's called Tension
When there is that force that pulls downward. Example, when you climb a mountain. You will fell that there is that gravity pulling downward.
A textbook on a table is an example of balanced forces. The force of gravity pulling the book downward is balanced by the normal force exerted by the table in the upward direction, resulting in the book remaining stationary on the table.

Remember Newton's Second Law! If the object is not accelerating, then of course they are balanced.The main forces are: 1) gravity pulling downward, the fluid in which it is floating pushing upward.
gravity at a downward force of 9.8m/s
His weight.
A light hanging from the ceiling does not move because the force of gravity pulling down on the light is balanced by the force of tension in the cord pulling upward
If the parachutist is just falling down vertically, he is falling because of the unbalance force. Gravity is pulling him down. Gravity is stronger than the air resistance that is "keeping him up". The two unbalanced forces: gravity & air resistance. Because they are imbalance, he is accelerating towards the Earth's surface at 9.8 meters per second.
'It's called Tension
Gravity . . . pulling you down. The scale . . . pushing you up. If these two forces were not equal, then there would be a net force on the bottom of your feet, either upward or downward, and you would be accelerating.
The opposing force in this situation is gravity pulling the magazine downward.
