Question

A simple pendulum completes 50 vibrations in 10 sec. find the frequency and time period of the vibrations.

Answer 1

frequency =50/10 = 5

time period = 1/frequency = 1/5

Answer 2

==================================

*⃣*⃣*⃣ WHAT WE KNOW ? *⃣*⃣*⃣


⏩ We know that the frequency is the number of vibrations made by a simple pendulum in one second.

==================================

Given, in 10 sec., no. of vibrations = 50

So, in 1 sec., no. of vibrations

= (50/10)

= 5 Hz (since this is frequency)

SO, THE FREQUENCY OF VIBRATION IS 5 Hz.

==================================

Also, Time period = 1/frequency

= 1/5 second.

= 0.2 second. [REQUIRED ANSWER]
