The mass of an electron is `9.1xx10^(-31)kg`. If its K.E. is `3.0xx10^(-25) J`, calculate its wavelength

Explanation

To calculate the wavelength of an electron given its mass and kinetic energy, we can follow these steps:

### Step 1: Write down the given values
- Mass of the electron, \( m = 9.1 \times 10^{-31} \, \text{kg} \)
- Kinetic Energy, \( KE = 3.0 \times 10^{-25} \, \text{J} \)

### Step 2: Use the kinetic energy formula to find the velocity
The kinetic energy (KE) of an object is given by the formula:
