Calculate the period of a ball tied to a

string of length 1.2 m making 5 revolutions
every second.
Answer in units of s

Freq. = 5rev/s.

Period = 1/5 = 0.2s.

To calculate the period of a ball tied to a string, we can use the formula:

Period = 1 / Frequency

Given that the ball makes 5 revolutions every second, the frequency is 5 Hz.

So, substituting the given value into the formula, we have:

Period = 1 / 5

Performing the calculation, we find:

Period = 0.2 seconds

Therefore, the period of the ball tied to a string is 0.2 seconds.
