Query: Melosh Rotation and the Nucleon Tensor Charge   By making use of the effect of the Melosh rotation, we show that one can
estimate, in a simple way, the nucleon tensor charge in a relativistic quark
model formulated on the light-cone. We discuss the physical significance of our
results and compare them with those recently obtained in different
phenomenological models.
