Five grams of helium having rms speed of molecules `1000 m//s` and `24 g` of oxygen having rms speed of `1000 m//s` are introduced into a thermally isolated vessel. Find the rms speeds of helium and oxygen individually when thermal equilibrium is attained. Neglect the heat capacity of vessel.

Explanation

To solve the problem, we need to find the root mean square (rms) speeds of helium and oxygen when thermal equilibrium is attained in a thermally isolated vessel.

### Step-by-Step Solution:

1. **Identify Given Data:**
- Mass of helium (m₁) = 5 g
- RMS speed of helium (v₁) = 1000 m/s
- Mass of oxygen (m₂) = 24 g
