An electron is accelerated through a potential difference of 100 V , then de-Broglie wavelength associated with it is approximately_____. `A^(@)`

Explanation

To find the de Broglie wavelength associated with an electron that has been accelerated through a potential difference of 100 V, we can follow these steps:

### Step 1: Calculate the kinetic energy of the electron
When an electron is accelerated through a potential difference (V), it gains kinetic energy (KE) given by the formula:
\[ KE = eV \]
where:
