Question

A simple pendulum takes 52 seconds to complete 10 oscillations.What is its time period?

2.1 s

5.1 s

52 s

5.2 s

​

Answer 1

$\LARGE{ \underline{\underline{ \bf{Required \: answer:}}}}$

GiveN:

• No. of oscillations = 10
• Time taken by the pendulum = 52

To FinD:

• Time period of the pendulum?

Step-by-step Explanation:

Time period is the time taken by a pendulum to complete one complete oscillation / cycle.

⇒ 10 oscillations = 52 seconds

⇒ 1 oscillation = 52 / 10 sec.

⇒ 1 oscillation = 5.2 s

Hence,

• The Time period of the pendulum is $5.2 \: s$ (Option D)

• Wavelength is another quantity which is the distance between any two consecutive crests/troughs or the length of one complete cycle.

• Wavelength is inversely proportional to frequency. Higher the frequency, lower is the wavelength.

Answer 2

Answer:

d) 5.2 s

Explanation:

Given:-

$10oscillations \: = 52seconds$

$1 \: oscillation \: = \frac{52}{10}$

$1 \: oscilllation \: = 5.2 \: seconds$

Therefore, the time period of the pendulum is 5.2 seconds
