Answer:
Given that from A to B & then B to the pendulum takes 3sec.
during one oscillation will move from C to B then B & C then C to A and A to C
⇒ Time taken to trans T
as time taken to travels C to B =
4
TT
arc(AC=CB)
⇒ time taken to travels from A to B
=
4
T
×2=
2
TT
Time taken to travel from B to C =
4
T
Now given that
2
T
+
4
T
=3sec
⇒T=4sec
= time period of on oscillation =4sec
= time period of 3.5 oscillation
=3.5×4=14sec.
