A small object is placed at the center of a large evacuated hollow spherical container. Assume that the container is maintained at 0K. At time t = 0 the temperature of object is 200K. The temperature of the object becomes 100K at `t = t_1` and 50K at `t = t_2`. Assume objectand container to be ideal black bodies. The heat capacity of object does not depend on temperature. Ratio `t_2/t_1` is
