L= g/π^2.
L = 9.81/(3.14^2),
L = 99.4m.

T = 2ω * L/G.

Put T= 2 Sec, G= 9.81 you get L = 0.994.

A seconds pendulum is a pendulum whose period is precisely two seconds; one second for a swing in one direction and one second for the return swing.

CALCULATION:

1 = (3.14^2) * L/9.81.

Then,
L = 0.994m.
