A book is lying on the horizontal table top. If we tilt the table a little, then the book starts sliding down slowly. This happens because:
(a) sliding friction is greater than static friction
(b) sliding friction is less than force of gravity
(c) static friction is greater than sliding friction
(d) force of gravity is less than sliding friction

B. A book of mass 1 kg is kept at rest on a table. The maximum value of static friction is 200 N and sliding friction is 180 N.
i. If we apply a force of 190 N, will the body move?
ii. If we apply a force of 210 N, will the body move?

Q. Answer the following question:

A. Why is sliding friction less than static friction for the same surface?

B. A book of mass 1 kg is at rest on the table. Maximum value of static friction is 5N and sliding friction is 4N.
