Change in the time period of a pendulum

Click For Summary
SUMMARY

The time period of a pendulum is directly influenced by its length, as established by the formula T = 2π√(L/g), where T is the period, L is the length, and g is the acceleration due to gravity. The discussion highlights confusion regarding the differentiation of the standard equation and the relationship between the new length of the pendulum with mass M and the old length without mass M. It is essential to clarify that the mass of the pendulum does not affect the time period, which solely depends on the length and gravitational acceleration.

Homework Statement
3.A pendulum made of a uniform wire of cross ` sectional area `A` has time period `T` .When an `additional mass `M` is added to its bob the time period changes to `T_(M)` .If the Young's modulus of the material of the wire is `Y` then `(1)/Y` is equal to ` `
Relevant Equations
T=2π√l/g
I tried taking log and then diffrentiate the standard equation for time period of a pendulum but i am not getting the correct answer

The period of a pendulum depends on its length. I don't understand your method at all.

Can you relate the new length of the pendulum (with mass ##M##) to the old length (without mass ##M##)?
