An `alpha` particle and a proton particle are moving on the surface of a-paper. A uniform magnetic field is normal on the paper. If the linear momentum of those two particles.are same then what will be the ratio of radii of them?

An alpha particle and a proton are moving in the plane of a paper in a region where there is uniform, magnetic field directed normal to the plane. If two particels have equal linear momenta, what will be the ratio of the radii of their trajectories in the field ?

An alpha -particle and a proton having same momentum ente into a region of uniform magnetic filed and paths r_a/r_p in the field is-

The path of a charged particle whose motion is perpendicular to a uniform magnetic field is

A beam of alpha particles and of the protons of the same velocity V, enter a uniform magnetic field at right angles to the field lines. The particles describe circular paths. What is the ratio of the radii of these two circles?

A charged particle enters a uniform magnetic field perpendicularly and experiences a force F. if the kintetic energy of the particle is doubled, then what will be the force on that particles ?

A particle of mass m is moving with a uniform velocity along a straight path parallel to the x -axis. Angular momentum of the particle with respect to the origin will be

An alpha - particle and a proton having the same momentum enter a region of uniform magnetic field and move in circular paths. The ratio of the radii of curvature of their circular paths r_(a)//r_(p) in the field is

The ratio of the masses and charges of a proton and an alpha particle are respectively 1:4 and 1:2 . They enter a uniform magnetic field of magnitude B normally with same momentum and What will be the ratio of the radii of the circular paths described by the particles in each case ?
