If three gas molecules have velocity 0.5, 1 and `2 km//s` respectively, find the ratio of their root mean square speed and average speed.

Explanation

To solve the problem of finding the ratio of the root mean square speed (Vrms) and the average speed (Vavg) of three gas molecules with velocities 0.5 km/s, 1 km/s, and 2 km/s, we will follow these steps:

### Step 1: Calculate the Root Mean Square Speed (Vrms)

The formula for the root mean square speed is given by:

\[
V_{rms} = \sqrt{\frac{V_1^2 + V_2^2 + V_3^2}{3}}
