q10 Sebastian has drawn a free-body diagram for a ladder of mass m leaning against a frictionless wallI. His diagram is shown below.What is his error?FNAFy is in the wrong direction.BIy should be directed upwards, not down.F, should be perpendicular to the wall, not parallel to it.D should be down into the floor for , to have the given direction.E y is correct, but there should also be a force perpendicular to the wall.N

Given: The wall is frictionless. The mass of the ladder is m.
