An electron move in a circular path of radius 2 cm under the influence of a magnetic field of 0.1 teals applied perpendicular to its plane of motion . Calculate the de Broglie wavelength of electron.

Explanation

To solve the problem of finding the de Broglie wavelength of an electron moving in a circular path under the influence of a magnetic field, we can follow these steps:

### Step 1: Convert the radius from centimeters to meters
The radius of the circular path is given as 2 cm. We need to convert this to meters for our calculations.

\[ \text{Radius} (r) = 2 \, \text{cm} = 2 \times 10^{-2} \, \text{m} \]
