A seconds pendulum $A$ (time period 2 s) and another simple pendulum $B$ of slightly less length are made to oscillate at $t = 0$ in the same phase. If they are again in the same phase first time after 18 s, the time period of $B$ is:

Answer:

1.80

Solution:

$B$ makes one more oscillation than $A$ in 18 s: $\frac{18}{T _{B}} - \frac{18}{2} = 1$ , so $T_{B} = 1.8$ s.
