6. In both cases, a massless rod is supported by a fulcrum, and a 200-kg hanging mass is suspended from the left end
of the rod by a cable. A downward force F keeps the rod at rest. The rod in case A is 50 em long, and the rod in
case B is 40 cm long. (Each rod is marked at 10-centimeter intervals.)

Will the magnitude of the vertical force F exerted on the rod be (a) greater in case A. (b) greater in case B, or (c)
the same in both cases?

answer

c, on a nylon carpet in a dry area. give me brainliest

explanation:

the answer for apex is the lowest

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
