Query: Cosmic censorship in overcharging a Reissner-Nordstr\"{o}m black hole
  via charged particle absorption   There is a claim that a static charged black hole (Reissner-Nordstr\"{o}m
black hole) can be overcharged by absorbing a charged test particle. If it is
true, it might give a counter example to the weak cosmic censorship conjecture,
which states that spacetime singularities are never observed by a distant
observer. However, so far the proposed process has only been analyzed within a
test particle approximation. Here we claim that the back reaction effects of a
charged particle cannot be neglected when judging whether the suggested process
is really a counter example to the cosmic censorship conjecture or not.
Furthermore, we argue that all the back reaction effects can be properly taken
into account when we consider the trajectory of a particle on the border
between the plunge and bounce orbits. In such marginal cases we find that the
Reissner-Nordstr\"{o}m black hole can never be overcharged via the absorption
of a charged particle. Since all the plunge orbits are expected to have a
higher energy than the marginal orbit, we conclude that there is no supporting
evidence that indicates the violation of the cosmic censorship in the proposed
overcharging process.
