The velocities of ten particles in `ms^(-1)` are `0,2,3,4,4,4,5,5,6,9`. Calculate (i)average speed and (ii)rms speed (iii) most probable speed. |

Answer» (i) average speed ,` V_(av) = (0+2+3+4+4+4+5+5+6+9)/10 = 42/10 = 4.2ms^(-1)` (ii) rms speed , `V_(rms) =[((0)^(2)+(2)^(2)+(3)^(2)+(4)^(2)+(4)^(2)+(4)^(2)+(5)^(2)+(5)^(2)+(6)^(2)+(9)^(2))/10]^(1//2)` =`[228/10]^(1//2) = 4.77ms^(-1)` (iii) most probable speed `V_(mp) = 4m//s` |
