Two H atoms in the ground state collide ...

Two H atoms in the ground state collide in elastically. The maximum amount by which their combined kinetic energy is reduced is

A

`10.20eV`

B

`20.40eV`

C

`13.6eV`

D

`27.2eV`

Text Solution

Verified by Experts

The correct Answer is:
A
The total energy associate with the two H-atoms in the ground state collide in elastically `=((13.6)/2^(2))+(13.6)=17.0eV`
"therefore" , maximum loss of their combined kinetic energy `=27.2-17.0=10.2eV`
