R.M.S. velocity of oxygen molecules at N...

R.M.S. velocity of oxygen molecules at N.T.P. is 0.5 Km/s. The R.M.S. velocity of he hydrogen molecule at N.T.P. is

A

4Km/s

B

2 Km/s

C

3 Km/s

D

1Km/s

Text Solution

Verified by Experts

Distance travelled, S`=ut+1/2at^2`
here, u=0, `a=(E_e)/(m_e)`
`S=0+1/2xx(E_e)/(m_e)xxat^2`
`:. S=1/2(E_e)/(m_e)t^2`
