Question
A particle executes simple harmonic motion under the restoring force provided by a spring. The time period is T. If the spring is divided in two equal parts and one part is used to continue the simple harmonic motion, the time period will
Options
A.remain T
B.become 2T
C.become T/2
D.become T/√2
Solution
Time period = T = 2π
∴ K become twice
Tnew = 2π
= 2π 
=
∴ K become twice
Tnew = 2π
= 2π =
