A He atom at 300 K is released from the surface of the earth to travel upwards. Assuming that it undergoes no collision with other molecules, how high will it be before coming to the rest?

A

9.53 m

B

9.5 m

C

953 m

D

`9.53xx10^(4)` m

Text Solution

Verified by Experts

The correct Answer is:
d
(d) `(3)/(2)KT=mgh`
`h=(3)/(2)xx(1.38xx10^(-23)xx300)/(9.81xx4xx1.66xx10^(-27))`
`=9.53xx10^(4)m`
