2.The normal force is the support force exerted upon an object that is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward force upon the book in order to support the weight of the book.
Gravitational pull on the mass of the body i.e. the weight of the body acting downwards perpendicular to the horizontal plane at which the body is resting. Normal reactive force exerted on the body by the horizontal plane which is exactly opposite to the direction of the above mentioned force.
