Question

When a body slides over the surface of the other, then the kinetic friction (f k) and static friction (f s) , are related us:

* (f k) < (f s)
* (f s) < (f k)
* (f k) = (f s)
* (f k) = 0​

Answer 1

Answer:

2. f(s) < f(k)

This is due to resistance developed due to sliding movement is more prominent then resistance to stop body in it's original position.

hope this will help you
