A simple pendulum has time period T 1 . When the point of suspension moves vertically up according to the equation y = kt 2 where k = 1 m/s 2 and ‘t’ is time then the time period of the pendulum is T 2 then 
is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
T 1 = 2 π 
= 2 π 
upward acceleration 
= 2k = 2 × 1 = 2 m/s 2
∴ Acceleration w.r.t. point of suspension = 12 m/s 2
T 2 = 2 π 
∴ 
= 
∴ 
= 
.
