Q1:

The length of a Second's pendulum, is

A 99.0 cm

B 99.4 cm

C 100 cm

D 101 cm

E 101.10 cm.

ANS:B - 99.4 cm

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.
