How much deflection would the electron beam suffer when it travels a distance of 10 cm in a uniform electric field of 20 N/C . The initial velocity of electrons is `3xx10^7` m/s directed perpendicular to the electric field .

Explanation

To solve the problem of how much deflection the electron beam suffers when it travels a distance of 10 cm in a uniform electric field of 20 N/C, we can follow these steps:

### Step 1: Identify the given values
- Electric field (E) = 20 N/C
- Distance traveled (d) = 10 cm = 0.1 m
- Initial velocity of electrons (v) = 3 x 10^7 m/s
- Charge of an electron (e) = 1.6 x 10^-19 C
- Mass of an electron (m) = 9.11 x 10^-31 kg
