A linear accelerator consists of a hundred brass discs tightly fitted into a steel tube. At `40^(@)C` the diameter of each disc is 10.02 cm. The system is assembled by cooling the discs in dry ice at `-60^(@)C` to enable them to slide into the close fitting tube. if the coefficient of linear expansion of brass is `2xx10^(-5).^(@)C^(-1)`, the diameter of each disc in dry ice will be
