उत्तर

Expression for a frequency of conical pendulum is given as:

f = `1/(2 pi) sqrt (g/(L cos theta)`

Here, f is the frequency, l is the length of pendulum and g is the acceleration due to gravity, and θ is the angle of inclination.

From the above expression, we can see that

  1. The frequency is directly proportional to the root of the acceleration due to gravity `f ∝ sqrt g`.
  2. The frequency is inversely proportional to the length of the pendulum `f ∝ sqrt(1/l)`.
  3. The frequency is inversely related to the angle of inclination `f ∝ sqrt(1/ (cos theta))`
  4. The frequency does not depend on the mass of the bob.
