The distance Δx between the points where the ions strike the detector is 0.0971 meters. In a mass spectrometer, ions are accelerated by a potential difference and then move in a circular path due to the presence of a magnetic field.
To solve this problem, we can use the equation for the radius of the circular path:
r = (m*v) / (|q| * B)
where m is the mass of the ion, v is its velocity, |q| is the magnitude of the charge, and B is the magnetic field strength. Since the ions are accelerated from rest, we can use the equation for the kinetic energy to find their velocity:
KE = q * V
where KE is the kinetic energy, q is the charge, and V is the potential difference.
Once we have the radius, we can calculate the distance Δx between the two points where the ions strike the detector. Since the ions follow circular paths with the same radius, the distance between the two points is equal to the circumference of the circle, which is given by:
Δx = 2 * π * r
By substituting the given values into the equations and performing the calculations, we find that Δx is approximately 0.0971 meters.
