Question

A source produces $200$ oscillations per $2$ seconds. Its time period is________.

• A. $0.01s$
• B. $0.01s$
• C. $0.01s$
• D. $0.02s$

Answer 1

The correct option is C $0.01s$

Given, source produces 200 oscillationns per 2 seconds.
Therefore, number of oscillations per second is $100$. We know, frequency is the number of oscillations produced per second.
Frequency $f$ = $100Hz$
Time period $T$ = $\frac{1}{f}$
Time period $T$ = $0.01s$
