    1. The problem statement, all variables and given/known data

    A rod is 6 m long pivoted at a point 1.5 m from the left end. Two downward forces of
    magnitude 50 N and 200 N are exerted on the left and right end of the rod
    respectively. At what distance from the pivot point must a third upward force of
    magnitude 300 N be exerted on the rod to keep it in rotational equilibrium? Neglect
    the weight of the rod.



    2. Relevant equations



    3. The attempt at a solution

    so apparently the answer for this question is "non of the above ".. I got an answer of 2.75, can someone check it for me plz?
