Question
The period of small oscillations of a simple pendulum of length l if its point of suspension O moves a with a constant acceleration α = α1 î − α2 ĵ with respect to earth is
Options
A.
B.
C.
D.
Solution
Point O is moving as shown
So acc. Of particle w.r.t O
= (−αî + (α2 − g)ĵ )
So geff. =
So time period
= 2π
So acc. Of particle w.r.t O
= (−αî + (α2 − g)ĵ )
So geff. =
So time period
= 2π
