Abstract：We study the massless Dirac perturbations of the fourdimensional Reissner-Nordstr(ǒ)m-like black holes with a tidal charge in the Randall-Sundrum braneworld in the first approximation when the tidal perturbations are not taken into account.It has been shown that the ability of the perturbative potentials to reflect the waves decreases with increasing value of the tidal charge, and then the position of peak moves forward to the right side along x-axis.By the third-order WKB approximation method, the low frequency numerical results of evolution of perturbation are carefully analyzed.Moreover, calculations have shown that black holes on the Randall-Sundrum braneworld are stable against the dynamical evolution of the massless Dirac perturbation.
