I have just answered 5 of your previous 6 questions.
You have shown no sign of any effort on your part.
Mmmhh, I wonder what makes me think that I am doing your assignment for you ?

Until I see some effort shown on your part, or some indication where your difficulties lie, .... no more replies from me.
T1 = 2π√27.5/√g
T1^2 = 4π^27.5g
T2 = 2π√27.5/√g
T2^2 = 4π^110g
T1^2/T2^2 = 4π^27.5g/4π^110g
T1^2/T2^2 = 27.5/110 = 275/1100 = 1/4
T1/T2 = √(1/4)
so T1: T2 = 1 : 2
