The forces at work are balanced. Gravity is pulling the book (and the rope) down, and the rope exerts an equal and opposite force to keep the book suspended.
When a crate is hanging from a rope that is attached, the force of gravity pulls the crate downward while the tension in the rope supports the weight of the crate.
Tension is the force that occurs in a rope when both ends are pulled in opposite directions. This force acts to stretch and elongate the rope.

The tension force in the string or support balances the force of gravity on a hanging light. This tension force is equal in magnitude and opposite in direction to the force of gravity acting on the light, keeping it in equilibrium.
If the pulley is fixed (hanging from the ceiling), and the rope passes over it, then 100 lbs of force is required. If the rope is fixed to the ceiling and passes under the pulley (which is fixed to the load), then 50 lbs of force is required.
Two forces acting on a hanging object are tension, which is the force exerted by the string or rope holding the object up, and gravity, which is the force pulling the object downward towards the Earth.
The tension in the rope is equal to the weight of the hanging block when the block is stationary and not accelerating.
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.
Force = mass X gravity therefore, 10 X 9.8 = 98 N ==================== -- Assuming that this is all happening near the earth, the 10 kg mass weighs 98 newtons. That means the force of gravity on it is 98 newtons, pointing straight down. -- Since it's just hanging there motionless and not accelerating either up or down, the net vertical force on it must be zero. -- The only other force on it besides gravity is the tension in the rope. -- In order for all the vertical forces on it to add up to zero, the tension in the rope must be exactly equal and opposite to the force of gravity ... 98 newtons pointing straight up.
The force on a rope is typically determined by the tension applied to it. This tension arises from the pulling or stretching of the rope, causing the rope to support a load or resist a force. The force on a rope can be calculated using principles of Newton's laws of motion and equilibrium.
The force exerted by the wall on the rope depends on the tension in the rope. This tension is equal in magnitude but opposite in direction to the force the rope exerts on the wall according to Newton's Third Law.
