The intensity of radiation emitted by the sun has its maximum value at a wavelength of \[510\ nm\] and that emitted by the north star has the maximum value at \[350\ nm\]. If these stars behave like black bodies, then the ratio of the surface temperature of the sun and north star is [IIT 1997 Cancelled; JIPMER 2000; AIIMS 2000]
