If a gas contains only three molecules that move with velocities of 100,200, 500 `ms^(-1)`. What is the rms velocity of that gas in `ms^(-1)` ?

Options

A. `100/y`
B. `100/30`
C. `100/I0`
D. `800/3`

Answer

c

Explanation

`C_(1) = 100 ms^(-1), C_(2) = 200 ms^(-1), C3 = 500 ms^(-1)`
rms velocity of the gas, `C =sqrt((C_(1)^(2)+ C_(2)^(2) + C_(3)^(2))/n)`
