We compare the effect of two body core on the charge form factor of3He by the hyperspherical harmonics expansion method using various 2BF potentials with the inclusion of three body force. We also include the meson exchange current contribution to the CFF for the same potentials in addition to the 3BF. The results indicate that the combined effect of 3BF and MEC (i) movesqmin2 (the first diffraction minimum) appreciably to the left, amount of shift depends on the 2BF atr12∼0.7 fm and (ii) enhancesFmax (the height of the secondary maximum of CFF) by an appreciable amount, the increment in general increases with the repulsive core of 2BF (r⩽0.1 fm).
