| **The book lies on the table, the weight of the book is 8 n, the area of its contact with the table is 0.08 m2. What is the pressure of the book.**

Answer: P = 100 Pa.

Explanation of the solution to the problem: to solve this problem, you must use the following formula:

P = F / S, where P is the pressure exerted on the body, in Pa (1 Pa = 1 N / (m ^ 2)); F is the force acting perpendicular to the surface, in n; S is the contact area in m ^ 2.

Substituting the values known from the condition of the problem into the formula, we obtain:

P = F / S = (8 n) / (0.08 m ^ 2) = 100 Pa.
