Destroying charged black holes in higher dimensions with test particles

A possible way to destroy the Tangherlini Reissner-Nordstrom black hole is discussed in the spirit of Wald's gedanken experiment. By neglecting radiation and self force effects, the absorbing condition and destruction condition of the test point particle which is capable of destroying the black hole are obtained. We find that it is impossible to challenge the weak cosmic censorship for an initially extremal black hole in all dimensions. Instead, it is shown that the near extremal black hole will turn into a naked singularity in this particular process, in which case the allowed range of the particle's energy is very narrow. The result indicates that the self-force effects may well change the outcome of the calculation.
