To study variation of time period of a simple pendulum of a given length by taking bobs of same size but different masses and interpret the result.
See Experiment 6.
The time period (T) of a simple pendulum for oscillations of small amplitude, is given by the relation,
T = 2π√(L/g) or T2 = (4π2/g) × L
∴ T ∞√L and T ∞ 1/(√g)
From the above equation, it clearly indicates that the time period of a simple pendulum is independent of mass i.e. for the same value of L and g, the time period of two bobs of different masses will be the same.
Vernier constant of the vernier callipers, V.C. = ______________ cm
Zero error, ±e = _____________cm
Least count of stop clock = ____________s
Zero error of stop clock = ___________s
Table 7.1 Determination of time-periods for same lengths of the different pendulum.
For the same value of effective length and acceleration due to gravity, the time period of bobs for different masses are same.
