A hydrogen isotope separator contains positively ionized hydrogen H^1, with isotope of hydrogen, Deuterium D^2, and other heavy particles, and the ions were released in a potential difference of 200 Volts. The strong magnetic field of 1.4x10^-2 Tesla (out of the page), bends the ions and Deuterium is collected on separate ionic trap as shown in the figure. (Masses MH1=1.67x10^-27 kg, MD2 = 2* MH1, Q(H1, D2) = 1.6x10^-19 C) What are the velocities of the Deuterium when exiting the plates, in unit of 10^5 m/s?
