The capacitance of an air-filled parallel-plate capacitor is 60 pF. When a dielectric slab
whose thickness is half the distance between the plates, is placed on one of the plates
covering it entirely, the capacitance becomes 86 pF. Neglecting the fringing effects, the
relative permittivity of the dielectric is _____________ (up to 2 decimal places).
