Four particles have velocities `1, 0,2, and 3 m//s`. The root mean square velocity of the particles (definition wise) is.

A

`3.5 m//s`

B

`sqrt(3.5) m//s`

C

`1.5 m//s`

D

`sqrt((14)/3)m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
`"cm s"=sqrt(((1)^2+(0)^2+(2)^2 +(3)^2)/4) = sqrt(3.5)m//s`
