Which of the following statements is true: (A) Using a positively charged rod, it is possible to charge an electroscope in a lab either positively or negatively. (B) Both conductors and insulators may hold a net charge

i'm only doing this for the points : (

explanation:

i'm only doing this the points

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.
