A book weighing 29 N is placed on a table. if the support force back on the book from the table is 29 N, what is the net force?
0 net force
To find the net force, we need to consider all the forces acting on the book. In this case, we have two forces: the weight of the book (29 N), which is the force due to gravity pulling it downward, and the support force from the table (also 29 N), which is pushing upward.
The weight of an object is always directed downward, while the support force is directed upward. Since these forces act in opposite directions, we can find the net force by subtracting the smaller force from the larger force.
In this case, both forces have the same magnitude (29 N). So, the net force can be calculated as:
Net Force = 29 N - 29 N = 0 N
Therefore, the net force on the book is zero.
