  We analyze the tidal forces produced in the spacetime of Reissner-Nordstr\"om
black holes. We point out that the radial component of the tidal force changes
sign just outside the event horizon if the charge-to-mass ratio is close to $1$
unlike in Schwarzschild spacetime of uncharged black holes, and that the
angular component changes sign between the outer and inner horizons. We solve
the geodesic deviation equations for radially falling bodies towards the
charged black hole. We find, for example, that the radial component of the
geodesic deviation vector starts decreasing inside the event horizon unlike in
the Schwarzschild case.
