1 point } A mass-spectrometer is being used to separate potassium 3%k (m=6.47 x 10726 kg) from 41k (m=6.80x 10726 kg). The potassium ions are each singly-ionized (Q=qp). The spectrometer is tuned such that the 39K travels a semicircular path, reaching the wall of the spectrometer a distance 8.69 cm away from the entrance. How far (in cm) from the entrance will the *1K ions impact
