A velocity selector uses a fixed electric field of magnitude E and the magnetic field is varied to select particles of various energies. If a magnetic field of magnitude B is used to select a particle of a certain energy and mass, what magnitude of magnetic field is needed to select a particle of equal mass but twice the energy?

◦
0.50 B

◦
1.4 B

◦
2.0 B

◦
0.71 B

◦
1.7 B
