With a fixed pulley, the effort force would be equal to the weight being lifted (300kg) in this case. So, to lift 300kg using a fixed pulley, you would need to apply an effort force of 300 kg-force.
The effort force required to lift a 300 kg weight using a fixed pulley system will be equal to the weight of the object being lifted. In this case, it will be 300 kg multiplied by the acceleration due to gravity (9.8 m/s^2), which equals 2940 N.
In a fixed pulley, the effort force is equal to the load force being lifted. The fixed pulley changes the direction of the force applied, but does not provide any mechanical advantage in terms of reducing the amount of effort needed to lift the load.
The three types of pulleys are fixed pulley, movable pulley, and compound pulley. Fixed pulleys are attached to a stationary object, movable pulleys move along with the load, and compound pulleys combine both fixed and movable pulleys to provide mechanical advantage.

Fixed Pulley and Compound Pulley.
Using a fixed pulley system, you would still need to exert the same amount of force as the weight you are trying to lift. So, to lift a 300 kg weight, you would need to exert a force equal to the weight (300 kg) times the acceleration due to gravity (9.81 m/s^2), which equals 2943 N.
Using a single fixed pulley will not change the amount of effort needed to lift a load. You will need to exert a force equal to the weight of the load, in this case 10 newtons, to lift it. The fixed pulley only changes the direction of the force needed, not the amount of force required.
In a fixed pulley system, the effort rope must move the same distance as the resistance (4m) in order to raise it by the same amount. This is because the fixed pulley changes the direction of the force applied, but does not provide any mechanical advantage in terms of distance.
A fixed pulley is different from a movable pulley because a movable pulley has one end of the rope attached to it fixed on an unmoving object. The pulley is free to move with the rope. You pull the other end of the rope. Also, a movable pulley multiplies the applied force (effort force) and therefore has more mechanical advantage. A fixed pulley is attached to something that doesn't move, while one end of the rope is holding the weight, while the other is for pulling.A fixed pulley confers no mechanical advantage, but will convert motion in one direction into another direction.A movable pulley system, if the pulleys change their distance from each other, will confer a mechanical advantage.
Oh, dude, the most effective pulley is the compound pulley system. It's like the rock star of pulleys, combining fixed and movable pulleys to give you some serious mechanical advantage. So, if you're looking to lift heavy stuff with minimal effort, that's the one you wanna go for.
