Question

Two gases exert pressure in the ratio 3: 2 and their densities are in the ratio 2: 3, then the ratio of their R.M.S. velocities is ...........

(a) 2:3

(b) 3:2

(c) 2:1

(d) 1:2

Solution

(b) 3:2

P= `1/3 ρc^2`

`c_1/c_2 = sqrt(P_1/P_2 xx rho_1/rho_2) = 3/2`

  Is there an error in this question or solution?
