An 1.0 kg mass book, initially at rest, is supported against a vertical wall, being pressed by a horizontal force of f 50 n module, as indicated in the figure. the acceleration of gravity has a modulus of 10.0m / s, the coefficient of static friction between the wall surface and the book is 0.25 and the coefficient of kinetic friction 0.20. mark the correct statement. a) the book slides along the wall and the modulus of the friction force is 10.0 n b) the book remains at rest and the module of the normal force of contact between the book is the wall is 10n c) the book remains at rest and the modulus of frictional force between the book and the wall is 12.5n. d) the book remains at rest and the modulus of frictional force between the book and the wall is 10 n e) the book slides along the wall and the module friction force is 12.5 n.
