We study the star matter properties for Hybrid equation of state (EoS) by varying the bag constant. We use the effective field theory motivated relativistic mean field model (E-RMF) for hadron phase with recently reported FSUGarnet, G3 and IOPB-I parameter sets. The results of NL3 and NL3 $ω ρ$ sets are also shown for comparison. The simple MIT bag model is applied for the quark phase to construct the hybrid EoS. The hybrid neutron star mass and radius are calculated by varying with $B^{1 / 4}$ to constrain the $B^{1 / 4}$ values. It is found that $B^{1 / 4} = 130$ –160MeV is suitable for explaining the quark matter in neutron stars.
