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

95.3 m

C

953 m

D

`9.53 xx 10^(4)` m

Text Solution

Verified by Experts

The correct Answer is:
D
`(3)/(2) KT = m gh, " " h = (3)/(2) xx (1.38 xx 10^(-23) xx 300)/(9.81 xx 4 xx 1.66 xx 10^(-27)) = 9.53 xx 10^(4)m`
