Root mean square velocity of a particle ...

Root mean square velocity of a particle is v at pressure P. If pressure is increased two times, then the r.m.s. velocity becomes

A

0.5 v

B

v

C

2 v

D

4 v

Text Solution

Verified by Experts

The correct Answer is:
B
`(C_(2))/(C_(1))=sqrt((3P_(1))/(rho_(1))xx(rho_(2))/(3P_(2)))=1`
Since, `(P)/(rho)` is constant.
`C_(2)=C_(1)=V`.
