A capacitor has two parallel plates seperated by 2mm and is connected across a 50V battery. a. What is the electric field between the field? b. What is the surface charge density? c. How much charge is stored on each plate if the area is 0.1m^2. d. Calculate the capicitance e. How much energy is stored in this capacitor?

a

e

Explanation:

From the question we are told that

   The distance of separation is

   The  voltage is

   The area is  

Generally the  electric field is mathematically represented as

=>    

=>    

Generally the capacitance  mathematically  represented  is

Here is the permitivity of free space with value  

=>      

=>      

Generally  the charge  is mathematically represented as

=>    

Generally the charge density is  mathematically represented as

=>  

=>  

Generally the energy stored in this capacitor is mathematically

=>  

=>  

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.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
