Question

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

Answer 1

the pendulum of the clock has time period 2.04sec. Now, No. or oscillation in 1 day = (24 × 3600)/2 = 43200 But, in each oscillation it is slower by (2.04 – 2.00) = 0.04sec. So, in one day it is slower by, = 43200 × (0.04) = 12 sec = 28.8 min So, the clock runs 28.8 minutes slower in one day.

Answer 2

Explanation:

For 1 sec time taken is

2

T

=1.02

ΔT=1.02−1

=0.02

This difference is generated in 1 sec

∴ in 24hrs

=0.02×60×24 min

=28.8min

∴28.8≅29min slower than the original clock
