Time period of second pendulum-xA0- T-2-xA0-sTime period-xA0- T-2-x3C0-x221A-lgwhere l is the length of pendulum-x2234-xA0-xA0- 2-2-x3C0-x221A-l9-8-x27F9-xA0-l-0-994-xA0-m-99-4-xA0-cm

The length of second pendulum is :

Time period of second pendulum $T = 2 s$
Time period $T = 2 π \sqrt{\frac{l}{g}}$
where $l$ is the length of pendulum.
$∴$ $2 = 2 π \sqrt{\frac{l}{9.8}}$
$⟹ l = 0.994 m = 99.4 c m$

The length of second pendulum is :

Time period of second pendulum T=2 sTime period T=2π√lgwhere l is the length of pendulum.∴ 2=2π√l9.8⟹ l=0.994 m=99.4 cm

Time period of second pendulum $T = 2 s$
Time period $T = 2 π \sqrt{\frac{l}{g}}$
where $l$ is the length of pendulum.
$∴$ $2 = 2 π \sqrt{\frac{l}{9.8}}$
$⟹ l = 0.994 m = 99.4 c m$
