= Which force? =

Friction, air resistance, tension, spring force, normal force, etc. are all due to

  A. Gravitational interaction
  A. Electromagnetic interaction
  A. Strong interaction
  A. Weak interaction

Ans. A.  An electromagentic interaction refers to the interaction of two electrically charged objects by exchanging photons.

= The force is everywhere =

When two objects exchange forces, they can do so without having to ''contact'' each other.

  A. Yes
  A. No

Ans. What do you mean by contact?  Does exchanging photons or gravitons count as contact?  On a more practical level, it is ''very'' helpful to remember, "no contact, no force except gravity," in ''most'' problems of classical mechanics.
