Question

76. For a particular experiment, helium ions are to be given a kinetic energy of 3.0 MeV. What should the voltage at the center of the ar celerator be, assuming that the ions start essentially at rest? A. -3.0 MV B. +3.0 MV C. +1.5 MV D. +1.0 MV

Answer 1

76.

KE = qV

3* 1.6* 10^—13 = 2* 1.6* 10^-19 V

V = 1.5 MV
