When the known mass is added to the string and put into oscillation,it drags the mass downwards. But in a case the length of the string is/was increased it cause the string to force the pendulum to travel a greater distance to complete a cycle, taing more time or more period resulting in fewer oscillation per second (lower frequency). As we all know that Period T= 2pie * squareroot of (L/g). Where a longer L result in a longer T. And Frequency F= 1/T. That is, higher the value of T result to lower the value of L. I believe you understand it now. if no consult page 350-370 under Simple Harmonic Motion in New School Physics or Page 134-145 under Simple Harmonic Motion in Hidden Facts in Physics or Chapter 12 under Simple Harmonic motion in All Inclusive Physics
