A pendulum clock (fitted with a small heavy bob that is connected with a metal rod) is 3 seconds fast each day at a temperature of 15 ° C and 2 seconds slow at a temperature of 30 ° C. Find the temperature (in ° C) at which it will show the correct time.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(24.00)
Fractional loss of time per second = 
Therefore 
(T 0 - 15) x (24hrs) = 3
and 
(30 - T 0 ) x (24hrs) = 2
on solving t 0 = 24 °C
