    The normal force of the wall on the ladderbalances the frictional force at the ground
    otherwise there would be a net horizontal force on the ladder.When the person stands
    at the top of the ladder the normal force by the wall is muchgreater in order to balance the
    greater torque produced by the person at the top of the ladder(using the contact with the
    ground as the axis of rotation). Thus the the frictional forceof the ladder with the ground
    must be greater to balance the normal force of the wall on theladder.
