  Recently in \cite{34}, the role of electromagnetic field on the cracking of
spherical polytropes has been investigated without perturbing charge parameter
explicitly. In this study, we have examined the occurrence of cracking of
anisotropic spherical polytropes through perturbing parameters like anisotropic
pressure, energy density and charge. We consider two different types of
polytropes in this study. We discuss the occurrence of cracking in two
different ways $(i)$ by perturbing polytropic constant, anisotropy and charge
parameter $(ii)$ by perturbing polytropic index, anisotropy and charge
parameter for each case. We conclude that cracking appears for a wide range of
parameters in both cases. Also, our results are reduced to \cite{33} in the
absence of charge.
