1.	Six molecules speed 2 unit , 5 unit , 3unit, 6 unit, 3 unit , and 5unit , respectively . The rms speed isA. 4 unitB. 1.7 unitC. 4.2 unitD. 5 unit
Answer» Correct Answer - C We have , `v_("rms")=sqrt((V_(1)^(2)+V_(2)^(2)+....+V_(n)^(2))/(n))` `=sqrt((4+25+9+36+9+25)/(6))` `sqrt((108)/(6))=sqrt(18)=3sqrt(2)=3xx1.414=4.242 ` unit
