Two strings of length l = 1 m each are tied to a horizontal rod and meet at a bob, each making 6 0 ∘ with the rod. The bob oscillates normal to the plane of the strings. Find the period, in s ( g = 9.8 ).

Effective length = l sin 6 0 ∘ = 0.866 m. T = 2 π 0.866/9.8 = 1.87 s.

Two strings of length $l = 1$ m each are tied to a horizontal rod and meet at a bob, each making $6 0^{\circ}$ with the rod. The bob oscillates normal to the plane of the strings. Find the period, in s ( $g = 9.8$ ).

Answer:

1.87

Solution:

Effective length = $l sin 6 0^{\circ} = 0.866$ m. $T = 2 π 0.866/9.8 = 1.87$ s.
