1.	A flask has 10 gas particles out of which four particles are moving at 7 ms−1 and all the remaining ones are moving at the speed of 'x' ms−1. If the Vrms of the gas is 5 ms−1, what is the value of ‘x′ ?
Answer» A flask has 10 gas particles out of which four particles are moving at $7 {ms}^{- 1}$ and all the remaining ones are moving at the speed of $' x' {ms}^{- 1}$ . If the $V_{r m s}$ of the gas is $5 {ms}^{- 1}$ , what is the value of $‘ x^{'}$ ?
