A spring has a certain mass suspended from it and its period for vertical oscillation is T. The spring is now cut into two equal halves and the same mass is suspended from one of the halves. The period of vertical oscillation is now.
A
B
C
D
2 T
Text Solution
Verified by ExpertsThe correct answer is:
B
T = 
. Also spring constant 
when the spring is half in length, then k becomes twice.
∴ T’ =
