# Two circular disks spacedapart form a parallel-plate capacitor. Transferringelectrons from one disk to the other causes the electric field strength to be. What are the diameters of the disks?

Diameter of disk is.

See the step by step solution

## Step 1: Formula for area and Electric field intensity

Electric field between capacitor is

Charge ischarge of electron.

Electric field due to parallel plate capacitor is,

## Step 2: Calculation for radius of disk

Substitute equationin equationthen value ofis given by,

## Step 3: Calculation for diameter of disk

Substitute in below formula,
