Question

A pendulum oscillates 50 times in 6 sec.Find its time period and frequency

Answer 1

Answer:

50 times in 6 sec means frequency = 50/6 Hz

f = 8.1Hz

T = 1/8.1

T = 0.12s

Answer 2

Given : A pendulum oscillates 50 times in 6 seconds.

　

To find : What is its time period and frequency?

　

Using formula :

1) Frequency = Number of times the pendulum oscillates/Total number of time taken.

　

2) Time period = Number of oscillation per second/Frequency.

　

Calculations :

→ Frequency = 50/6

→ Frequency = 8.33333333 hertz

　

→ Time period = 1/6

→ Time period = 0.12 seconds

　

Therefore,

1. Frequency = 8.33333333 hertz.
2. Time period = 0.12 seconds.
