An insulated chamber at a height h above the earth’s surface and maintained at 30∘C has a clock fitted with an uncompensated pendulum. The maker of the clock for the chamber mistakenly designs it to maintain correct time at 20∘C at that height. It is found that if the chamber were brought to earth’s surface the clock in it would click correct time at 30∘C. The coefficient of linear expansion of the material of pendulum is (earth’s radius is R): |
