We perform the calculation of nuclear matrix elements for the neutrinoless double beta decays under a Left-Right symmetric model mediated by light neutrino, and we adopt the spherical quasi-particle random-phase approximation (QRPA) approach with realistic force. For eight nuclei: Ge, Se, Zr, Mo, Cd, Te, Te and Xe, related nuclear matrix elements are given. We analyze each term and the details of contributions of different parts are also given. For the term, we find that the weak-magnetism components of the nucleon current contribute equally as other components such as axial-vector. We also discuss the influence of short-range correlations on these NMEs. It is found that term are more sensitive to the short range correlation than other terms due to the large portion of the contribution from high exchange momenta.
