Until now, the effect of gravity has been neglected. Estimate (by calculation) the effect of gravity on neutrons in a SANS instrument with \(L_{\rm c} = L_{\rm d} = 6\) m for neutrons of 10 Å and 20 Å. Comment on the result, but continue to not include gravity in the next problems.

Hint

Consider the neutrons classical particles moving in parabolas.
