Answer the following questions:
(a) The motion of a simple pendulum is approximately simple harmonic for small angle oscillation. For larger angles of oscilliation, a more involved analysis shows that `T` is greater than `2pisqrt((t)/(g))` Think of a qualitative argument to appreciate this result.
(b) What is the frequency of oscillation of a simple pendulum mounted in a cabin that is freely falling under gravity ?

Text Solution

Verified by Experts

The pendulum is in a state of weightlessness i.e. `g = 0`. The frequency of pendulum `v=1/(2pi)sqrtg/l=0`

Answer the following questions: (a) Time period of particle is S.H.M. depends on the force constant k and mass m of the particle : T=2pisqrt(m//k). A simple pendulum executes S.H.M. approximately. Why then is the time-period of a pendulum independent of the mass of the pendulum? (b) The motino of simple pendulum is approximatley simple harmonic for small angles of oscillation. For large angle of oscillation, a more involved analysis (beyond the scope of this book) shows that T is greater that 2pisqrt(l//g) . Think of a quanlitative argument to appreciate this result.

Sandeep constructed a simple pendulum to find the value of 'g' at that place. He observed that the bob of a simple pendulum moves from the mean position to one of the extreme positions in 0.5 s. Using this he determined the (i) time period of the simple pendulum. (ii) number of oscillations the pendulum has under - gone in four seconds and (iii) the frequency of oscillation of the pendulum. What are his answers ?
