A pendulum clock gives correct time at 20∘ C at a place where g = 9.800 ms−2. The pendulum consists of a light steel rod connected to a heavy ball. It is taken to a different place where g 9.788 ms−2. At what temperature will it give correct time ? Coefficient of linear expansion of steel =12×10−6 ∘C−1 |
