According to the properties of conductor,
Statement – I is true as body of conductor acts as equipotential surface and the electric field inside the conductor is zero.
Statement – 2 is also true as conductor is equipotential. Tangential component of electric field should be zero. Therefore electric field should be perpendicular to surface.
