500N
The force needed to lift a weight of 200N would be 200N. This is because the force needed to lift an object against gravity is equal to the weight of the object itself.
The minimum amount of force needed to lift an object can be found by calculating the object's weight using the formula F = m * g, where F is the force, m is the mass of the object, and g is the acceleration due to gravity. This force must be greater than or equal to the weight of the object to lift it off the ground.
The weight of an object is directly proportional to the pulley tension required to lift it. This means that as the weight of the object increases, the tension in the pulley system needed to lift it also increases.
A pulley system can increase one's mechanical advantage by distributing the force needed to lift an object over multiple ropes and pulleys, making it easier to lift heavy objects. This can make it feel like you have increased power when using a pulley system compared to lifting the object directly.
A moveable pulley reduces the amount of input force needed to lift an object. By attaching the pulley to the object being lifted, the force needed to move the object is distributed between the pulling force and the weight of the object itself, making it easier to lift.
400 N 400 N / 10cm2 = 2000 N / 50cm2
The force needed to lift a weight of 200N would be 200N. This is because the force needed to lift an object against gravity is equal to the weight of the object itself.

The longer the inclined plane, the less force is needed to lift an object. This is because the incline reduces the amount of vertical lift required by converting it into a smaller force acting over a longer distance. A longer inclined plane allows the force to be applied more gradually, making it easier to lift the object.
A pulley helps lift an object by reducing the amount of force needed to lift it. When a rope is threaded through a pulley, it allows you to pull down on one end of the rope while the object is lifted up on the other end, distributing the weight between multiple ropes and making it easier to lift the object.
The work done to lift the object is 200 J (Work = Force x Distance). The power exerted to lift the object is 40 watts (Power = Work / Time).
