Given the amount of work required to move a box 5 meters across the floor is 100j. what is the force that is needed? 20 n 25 n 75 n 100 n

20n = 20newton

Explanation: I just learned about this in my lesson and got it right on the quiz hope this helps you on your quiz I don't know how to really explain it but I did get it right trust me...

:P

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
