Question

Two pendulums of length 1m and 16m when they will be in phase again ?

Answer 1

LET the time periods of two pendulums are T1 and T2 . From the question T1=T2/4. so when the first pendulum will complete its four oscillations the bigger one will complete its one oscillation. So they will be in phase for n=4

Answer 2

Answer:

4

Explanation:

4 oscillation of smaller and 1 oscillation of larger
