विकल्प

• 25 keV

• 50 keV

• 200 keV

• 100 keV

Answer 1

A deuteron of kinetic energy 50 keV is describing a circular orbit of radius 0.5 metre in a plane perpendicular to the magnetic field B. The kinetic energy of the proton that describes a circular orbit of radius 0.5 metre in the same plane with the same B is 100 keV.
