    a body keep in a ground is not a action reaction case.. action and reaction always acts on different objects.. body places in ground is equilibrium case where two forces balance each other(normal force balance it's weight)

    when a body is placed on ground, the normal force acting on it is not the reaction of m*g (its weight). this normal force cancles the weight. hope this helps. ask doubts if any.
