Why is the normal force from point E not equal to the mass t

Why is the normal force from point E not equal to the mass times gravity due to the fact that there are no other forces acting at that point?

Solution

Normal force is only the balancing force . At certain times it is equal to be mass times gravity but it does not need to be mass times gravity all the time.

If only gravity is acting , but the surface at which the thing is kept is elevated or depressed by some angle, then the normal force will not be equal to mass times gravity.

If only gravity is acting and the object is at horizontal level , and instead of the whole object being in contact with the surface, the object is only in contact at certain finite fixed number of points , then also the normal force will not be equal to mass times the gravity.
