Equal number of \( H e \) and \( N e \) atoms are placed in two flask of volume \( V_{1} \) and \( V_{2}\left(V_{1}V_{2}\right) \) respectively and temperature of both vessels are same \( 400 \mathrm{~K} \). Then identify the correct statement(s):
(A) \( \left(\mathrm{U}_{\mathrm{rms}}\right)_{\mathrm{He}}=\left(\mathrm{U}_{\mathrm{rms}}\right)_{\mathrm{Ne}} \)
(B) Average \( \mathrm{KE}_{\mathrm{He}}= \) Average \( \mathrm{KE}_{\mathrm{Ne}} \)
(C) \( \mathrm{P}_{\mathrm{He}}\mathrm{P}_{\mathrm{Ne}} \)
(D) \( \mathrm{P}_{\mathrm{He}}\mathrm{P}_{\mathrm{Ne}} \)
\( P \)
