As the title states, I was wondering if an object that is at rest in a horizontal, v-shape channel like the one in this diagram would experience static friction:

No it won't. Because the net force on it is zero.

Consider a frictionless case. The object will be at rest. Meaning net force is zero. So in the given case no need for frictional force to act.

    $\begingroup$ No, reaction force from opposites side and gravitational force balances out. Each interaction between objects is not necessarily done only through frictional force. $\endgroup$ – Likhon Oct 20 '19 at 7:13

    $\begingroup$ A ball at rest on ground has no frictional force acting on it. It's simply a perpendicular reaction force. $\endgroup$ – Likhon Oct 20 '19 at 7:16
