The thunderstorm events observed by GRAPES-3 muon telescope can be studied with aid of Monte Carlo simulations. One such event observed on 1 December 2014 was analysed and its electrical properties of thundercloud were derived using muon imaging. This recent result showed production of Giga-Volt potential in thunderclouds, possibly responsible for production of 100 MeV $\gamma$-rays in terrestrial $\gamma$-ray flashes. However, these properties derived from simulations rely on choice of low and high energy hadronic interaction models used in CORSIKA. So, the derived properties are model dependent which makes this study very important. The comparison of various combinations using low and high energy hadronic models and its impact on electric potential estimation will be discussed in this work.
