Question

b) A simple pendulum makes 50 oscillations in 10 seconds. Its time period (T) and
frequency (F) are:
(i) T = 10 seconds and F = 50 Hz
(ii) T = 5 second and F = 0.2 Hz
(ii) T = 0.2 seconds and F = 5 Hz
(iv) T = 5 seconds and F = 50 Hz​

Answer 1

Answer:

option c is correct one.

T = time to complete one oscillatory motion

T = 50/10

= 5 seconds

Now,

f = 1 / t

=1 / 5

= 0.2 Hz
