  By using electromagnetic form factors predicted by Generalized Chou Yang
model (GCYM), we compute root mean square (rms) radii of several hadrons with
varying strangeness content (number of strange quarks/anti-quarks) such as
(pion, proton, phi0, Lambda0, Sigma+, Sigma- and Omega-) The computed radii are
found quite consistent with the experimental results and those from other
models (for pion and proton). For hadrons other than pion and proton, the
experimental results are not available and also the GCYM and other models
results are not consistent with each other. The computed rms radii (from GCYM
and other models) indicate that rms radii decrease with increase in strangeness
content, separately for mesons and baryons. The experimental results of hadrons
other than pion and proton will throw more light on the suitability of GCYM and
other models.
