The answer to this question is 50. Those who are not too familiar with the different formulas that are used in physics may have no idea how this is the correct answer. It is best to check out the given. The formula that will be used for this is F1D1=F2D2. 200N (20)/50. The answer to this will be 50.
The right amount of force is important because of different reasons. There are some items that will break down when you use too much force. There are also some items that will not move at all when you do not exert the right amount of force that the item needs.
F1*d1=F2*d2 F1 is 200N because that is the only force mentioned in the question d1 is 20cm because that's the distance of F1 from the pivot d2 is80 cm because that is the distance of F2 from the pivot (60+20) MakeF1the subject F1= (20*200)/50 F1= 50N
