Answer:
T ' = √2 T
Step-by-step explanation:
Given that
Time period = P
Frequency = T
We know that time period for pendulum given as
When the length become half then time period will become p'
L'=L/2
It means that time period will become 0.707 P.
We know that frequency T
T= 1 /P
T' = 1/P'
T'=√2/P
T ' = √2 T
