  We calculate the Newtonian potential in the two-brane Randall-Sundrum model,
emphasizing the effect of the finite distance between the two branes. The
result obtained is quite natural: When the distance in the potential is small
compared to the brane separation the two-brane model is indistinguishable from
the one-brane model, whereas when the distance is large the bulk dimension
behaves like an ordinary compact dimension, with an exponentially decreasing
correction to the four-dimensional potential. The contribution from the radion
is also included, and is found to give only a multiplicative factor of order 1
in the correction.
