Two circular disks spaced 0.50 mmmm apart form a parallel-plate capacitor. Transferring 1.30 x10^9×109electrons from one disk to the other causes the electric field strength to be 3.10 x10^5 N/C×105N/C

\

\

Step 1:

\

The electric field strength between the two circular disks is $\"\"$ .

\

Number of electrons transferring from one plate to another $\"\"$ .

\

Total Charge $\"\"$ , where

\

$\"\"$ is the number of electrons.

\

$\"\"$ is the electron charge( $\"\"$ ).

\

$\"\"$

\

Step 2:

\

Find the total charge on the two circular disks.

\

Total charge $\"\"$ , where

\

$\"\"$ is the capacitance of the two circular disks $\"\"$ .

\

$\"\"$ is the voltage across the two circular disks $\"\"$ .

\

$\"\"$

\

Here $\"\"$ is the area of the circular disks $\"\"$ .

\

$\"\"$ is the permittivity of free space $\"\"$ .

\

$\"\"$

\

$\"\"$

\

Diameter of the disk is $\"\"$

\

Solution:

\

Diameter of the disk is $\"\"$ .
