There are six books in a stack, and each book weighs 5 N. The coefficient of static friction between the books is 0.2. With what horizontal force must one push to start sliding the top 5 books off the bottom one.

my answer is 3N but i don't think that's right.

does anyone know what the answer is ..?

five books weigh 25 N

.2 *25 = 5N

Aren't there five books on top, so the normal force is 25N?

Friction=mu(normal force)
