A metal target with atomic number Z=46 is bombarded with a high energy electron beam. The emission of X-rays from the target is analyzed. The ratio r of the wavelengths of the K_\alpha-line and the cut-off is found to be r=2. If the same electron beam bombards another metal target with Z=41, the value of r will be [JEE Adv 2024 P2]
