If velocities of 3 molecules are 5 m/s, -6m/s and 7 m/s respectively,

1.	If velocities of 3 molecules are 5 m/s, -6m/s and 7 m/s respectively, then their mean squar evelocity in `m^(2)//s^(2)`A. `11m^(2)//s^(2)`B. `36.7m^(2)//s^(2)`C. `6m^(2)//s^(2)`D. `2m^(2)//s^(2)`
Answer» Correct Answer - B `C^(2)=(C_(1)^(2)+C_(2)^(2)+C_(3)^(2))/(3)=(25+36+49)/(3)` `=(110)/(3)=36.66`
