Conical Pendulum

    I can do the first part, however am unsure of how to deduce the motion cannot take place unless the inequality is satisfied. Can someone please explain this part?

    Assume the opposite inequality holds, and plug it into the equality you got (giving you an inequality) and see if a contradiction pops up
