JEE Main 2014 Physics question
A gas molecule of mass M at the surface of the earth has kinetic energy equivalent to 0 °C. If it were to go up straight without colliding with any other molecules, how high it would rise? Assume that the height attained is much less than the radius of the earth. ( is Boltzmann constant)
Answer: (2)
Solution
The kinetic energy corresponding to 0 °C = 273 K is $ =
