Because it's five times heavier of course !
The answer would depend on the units used for the force. Since these are not specified, it is not possible to answer the question.
to balance moment 10 feet x force = 2 feet x 200 force = 40 pounds
Lift lbf = (Normal force lbf) x (cosine of angle of attack)
Lift
Measure how much it can lift.
You exert a force of 30 N.
A minimum of 1.667 newtons.
20lbs
Work done equals force times distance, so 10.0 times 0.9 is 9 joules.
The distance is longer than the lift or the drop, but the force you need is less than the weight of the load.
Because there is a force of gravity constantly pulling it towards the center of earth. When you exert enough force to over come the gravity acting on an object it is lifted
The answer would depend on the units used for the force. Since these are not specified, it is not possible to answer the question.

No matter how much force you exert downward, it shall avail you naught. No downward force acting directly on the object can ever succeed in lifting it.
your muscles burn when you exert yourself because when you lift heavy or lift for an excess ammount of reps you get a build up of lactic acid in your muscles
If the question is asking "for what reason would a person lift a heavy stone immersed in water as opposed to air?" then the answer is buoyancy. When immersed in water there will be an upward force on the bottom of the stone due to the volume of water it has displaced. This upward force will make the stone seem lighter to the person lifting it by decreasing the amount of force they need to exert to lift it.
