The period of ' T' of oscillation of a simple pendulum depends upon length'l ' andacceelatacce due to gravity g'.Let us derive the relation between T,l and g
Let Time period =TMass of the bob = mAcceleration due to gravity = gLength of string = L Let ⇒a=0 ⇒ Time period of oscillation is independent of mass of the bob -2b=1⇒b=- b+c = 0- + c =0c= Giving values to a,b and c in first equation The real expression for Time period is Therefore time period of oscillation depends only on gravity and length of the string.Not on mass of the bob.
