I can not find the answer for this

In a rotating frame of reference, Newton's first and second laws remain valid if we assume that a fictitious force equal to mv^2/r is acting. What effect does this assumption have on the validity of Newton's 3rd law?

What do you think the effect is? If you always have to add a force to anything that's happening?
