Problem 14CQ
Suppose you press your physics book against a wall hard enough to keep it from moving. Does the friction force on the book point (a) into the wall, (b) out of the wall, (c) up, (d) down, or (e) is there no friction force? Explain.
ANSWER:
Step 1 of 2
We have to find which way is the frictional force acting.
The force exerted by the hand balances the normal force acting on the book due to the surface of the wall.
