A relativistic model of independent quarks based on Dirac equation with an equally mixed scalar-vector square root confining potential is used to compute the quark core contributions to the static properties like magnetic moments, charge radii and axial vector coupling constant ratios of the baryon octet. The results obtained with appropriate corrections due to centre-of-mass motion agree fairly well with experimental values. The model is also extended to the study of magnetic moments of the quark core of baryons in the charmed andb-flavoured sectors and the overall predictions so obtained compare well with other model predictions.

The nucleon electromagnetic form factorsG_E^P(q²),G_M^P(q²) and the axial-vector form factor G_A(q²) are studied in a relativistic model of independent quarks confined by an equally mixed scalar-vector square root potentialV_q(r)=1/2(1+γ⁰)(ar^1/2+ν₀) taking into account the appropriate centre-of-mass corrections. The respective root-mean-square radii associated withG_E^P(q²) and G_A(q²) come out as [〈r²〉_E^P]^1/2=0.86 fm and 〈r_A²〉^1/2=0.88 fm. Restoration of chiral symmetry in this model is discussed to derive the pion-nucleon form factorG_πNN(q²) and consequently the pion-nucleon coupling constant is obtained asg_πNN(q²)=12.81 as compared tog_πNN(q²)_exp⋍13.
