Question
Two pendulums begin to swing simultaneously. The first pendulum makes 9 full oscillations when the other makes 7. Find the ratio of length of the two pendulums.
Options
A.
B.
C.
D.
Solution
Given time for both are same
9T1 = 7T2
9 × 2π
= 7 × 2π
⇒ 9
= 7 
⇒ 
9T1 = 7T2
9 × 2π
= 7 × 2π⇒ 9
= 7 ⇒ Create a free account to view solution
