JEE Main 2016 Physics question
A pendulum clock loses 12 s a day if the temperature is C and gains 4s a day if the temperature is C. The temperature at which the clock will show correct time, and the co-efficient of linear expansion of the metal of the pendulum shaft are respectively:
Answer: (3)
Solution
Since and , the fractional change in period is . If the clock reads correctly at , the time lost or gained per day is s.
