Question

A pendulum oscillates 200 times in 50 seconds. Find the time period and

frequency.​

Answer 1

Answer:

4

Explanation:

time period= no. of oscillation ÷ time in sec.

= 200 ÷50

=4

Answer 2

Time period = time taken by one oscillation.
Time taken by 200 oscillation: 50 secs
Time taken by 1 oscillation: 50/200
: 1/40 secs
To find frequency:-
Time period = 1/ frequency
Hence,
Frequency = 1/ time period
= 1/ 1/40
1 X 40
40 Hz
