Dielectrics (Please, somebody should help me out. )

[Mozart]

a parallel plate capacitor has plates of dimensions 20cm by 20cm seperated by 2mm. The dielectric constant of the material between the plates is 5 and the plates are connected to a voltage source of 500V. calculate (a) the capacitance, (b) the charge on either plate, © the energy density, and(d) the total energy stored in the capacitor.

What have you done so far too try and solve the?

[daniton]

Why do you post this question?

because you don't know........

[John Cuthber]

Because we help with homework, we don't do it for you.

[daniton]

Because we help with homework, we don't do it for you.

Actually I didn't ask you sorry for the confusion. It was for OP.

[John Cuthber]

So, you asked someone who posted a question in the homework help section why they posted that question.

I'm going to stick my neck out and suggest it's because it's a homework question, and they wanted help with it.

[daniton]

you don't get my point I was trying to know what the OP didn't understand and don't be silly everybody know why somebody posts in homework thread ,to get help.

Hey. Please, I'm sorry. I actually needed help, but have gotten one now. I have managed to produce the solution myself. thanks all.

[John Cuthber]

Hi Mozart, glad you got it sorted.

[daniton]

Mozart, don't you know how to calculate capacitance of a capacitor it is the first lesson when you begin capacitor after definition.
