Air breaks down and conducts charge as a spark if the electric field magnitude exceeds v/m. determine the maximum charge that can be stored on an air-filled parallel-plate capacitor with a plate area of . a air-filled parallel-plate capacitor stores charge . find the potential difference across its plates.

Explanation:

Suppose

Magnitude of Electric Field is E V/m

Area of the cross-section is A

capacitor

Distance between Area of capacitor is d

Maximum Charge stored is

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.
