If we drop a charged particle and a neutral particle at the same time(same hight) in a uniform gravitaional field, they will hit the ground simultaneously?(adsbygoogle = window.adsbygoogle || []).push({});

on one hand：a freely falling charged particle will radiate according to a supported observer, so the radiation recoil (radiation damping) wil decelerate the charged particle,the neutral particle will hit ground first.

on the other hand: a freely falling charged particle will not radiate according to a freely falling observer,so the two particles will hit the ground simultaneously.

how to solve this paradox?
