The normal force acting on the book by the inclined plane is most nearly 17N.
<h3>What is the normal force?</h3>
When a body is resting on the surface, the reaction force acting perpendicular to the surface of contact and in upward direction is equal to the the weight of the object.
On an inclined plane of 30 degree, a 2 kg block is resting. Its weight mg has two components, mgcos30 and mgsin30.
The Normal force will be equal to
N = mgcos30
N =2 x 9.81 x cos30
N = 17 Newtons
Thus, normal force acting on the book by the inclined plane is most nearly 17N.
