Question

Proove C=epsilon not•d upon A
​

Answer 1

Explanation:

Since, C=q/V-------(1)

& We know that charge on plates is

Sigma×area. (As sigma =q/A)

&V=E×d

We also know that E field between the plates is sigma /ebsilnot

So, V=sigma×d/ebsilnot

Now,

By putting values of charge &Voltage

We get

C=sigma×area/sigma×d/ebsilnot

So, C=(ebsilnot×A)/d

Hence proved
