Question

Imagine that the little atom approaches the big atom from infinity with an initial kinetic energy K = 5 x 10^-21 J. How close to the big atom does it get? I know the answer (x = 0.3 nm) already but I dont know how to get it. And I also want an explantion.

Explanation / Answer

you read the chart from right to left (when the atom approaching from infinity) by horizontal line K = 5
