Answer:
Time period for Simple pendulum,
Explanation:
The Simple Pendulum
Consider a small bob of mass is tied to extensible string of length that is fixed to rigid support. The bob is oscillating in the plane about verticle.
Let is the angle made by string with vertical during oscillation.
Vertical component of the force on bob,
Negative sign shows that its opposing the motion of bob.
Taking as very small angle then,
Let is the displacement made by bob from its mean position ,
then,
so, ........(1)
Since, pendulum is in hormonic motion,
as we know,
where is the constant and
.........(2)
From equation (1) and (2)
Since,
