An electron and a proton having same momenta enter perpendicularly to a magnetic field, then

Force on a charge in electric and magnetic fields A charge particle follows a parabolic path in a uniform electric field and a charged particel moving in a uniform magnetic field has two kinds of motions lnear motion in the direction of magnetic field and circular motion in a plane perpendicular to the magnetic field. when charge q is moving perpendicular to the magnetic field B, the radius of the circular path is r=(mv)/(Bq) . If v and B makes an angle theta , then r=(mvsintheta)/(Bq) , and the time period T=(2pim)/(Bq) . If an electron and a proton having same momenta enter perpendicular to a magnetic field, then

An electron and a proton with equal momentum enter perpendicularly into a uniform magnetic field, then

An electron and a proton with equal momentum enter perpendicularly into a uniform magnetic field, then

If electron and proton having same momenta enter normally to a magnetic field then

Ionized hydrogen atoms and alpha -particles with same momenta enters perpendicular to a constant magnetic field, B. The ratio of their radii of their paths r_(H):r_(alpha) will be :

The mass of a proton is 1840 times that of an electron. An electron and a proton, with equal kinetic energies, enter perpendicularly uniform magnetic field. Now ______ .

An electron and a proton have equal kinetic energies. They enter in a magnetic field perpendicularly, then
