Correct option is B
The correct answer is (b) 2 seconds.
Explanation:
● The Time Period of a pendulum is the time taken to complete one full oscillation
● Calculation: Time Period = Total Time / Number of Oscillations.
● 60 seconds / 30 oscillations = 2 seconds.
Information Booster:
● Frequency is the reciprocal of the time period (Number of oscillations / Time).
● For this pendulum, the frequency is 0.5 Hz (30/60).
Additional Knowledge:
● The time period of a simple pendulum depends on its length and the acceleration due to gravity (g).
● It is independent of the mass of the bob.
