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
`v_(rms) = sqrt(((1)^(2) + (0)^(2) + (2)^(2) + (3)^(4))/(4))`
= `sqrt(3.5) m//s`.
