Question

The pendulum of a certain clock has time period 2.04s. How fast or slow does the clock run during 24 hours?

✓

Answer

The pendulum of the clock has time period 2.04sec.
Now, No. or oscillation in 1 day $=\frac{24\times3600}{2}=43200$
But, in each oscillation it is slower by $(2.04-2.00)=0.04\sec.$
So, in one day it is slower by,
= 43200 × (0.04) = 12sec = 28.8min
So, the clock runs 28.8 minutes slower in one day.
