Question
A simple pendulum has time period 2s. The point of suspension is now moved upward accord intro relation y = (6t - 3.75t2) m where is in second and y is the vertical displacement in upward direction. The new time period of simple pendulum will be
Options
A.2s
B.1s
C.4s
D.None of these
Solution
T1 = 2s = 
, T2 = 
, where g′ = g + 
= 10 - 7.5 = 2.5 = 
⇒ T2 = 
2 × 2 = 4s
, T2 = , where g′ = g + = 10 - 7.5 = 2.5 = ⇒ T2 = 2 × 2 = 4sCreate a free account to view solution
