Question

The RMS velocity of a gas is 3.5*10^4 cm/ sec the most probable velocity of the molecule is ​

Answer 1

Answer:

Correct option is

A

2.856 × 10  

4

 cm/sec

The RMS velocity of the gas is = 3.5×10  

4

 cm/sec

Most probable velocity =  

M

2RT

​

 

​

 

M

3RT

​

 

​

=3.5×10
