The relation between velocity of sound in a gas (v) and r.m.s. velocity of molecules of gas \( \left(\mathrm{v}_{\text {r.m.s. }}\right) \) is
(a) \( \mathrm{v}=\mathrm{v}_{\text {r.m.s. }}(\gamma / 3)^{1 / 2} \)
(b) \( \mathrm{v}_{\text {r.m.s. }}=\mathrm{v}(2 / 3)^{1 / 2} \)
(c) \( v=v_{\text {r.m.s. }} \)
(d) \( \quad \mathrm{v}=\mathrm{v}_{\text {r.m.s. }}(3 / \gamma)^{1 / 2} \)
