A device is used to measure the charge-to-mass ratio (e/m) of ions by accelerating them using an electric field described by a potential difference , and once they have acquired kinetic energy of known amount, they enter a uniform magnetic field. The particles move in a plane perpendicular to the magnetic field. What is the mass of the ion that enters the detector? Strength of magnetic field = 0.8 T d = 6.00 cm ΔV = 100 V Ion charge = 1.6 x 10^-19 C I'm not really sure how to set up an equation here. I tried using qΔV = 1/2 mv2 and F = ma = qvB sin theta to solve it but I couldn't figure out how to solve for m here. Is there another formula I should use?
