Two protons P and Q moving with the same speed enter magnetic field `B_(1)andB_(2)` respectively at right angles to the field directions. If` B_(2) `is greater than `B_(1)` for which of the protons P and Q the circular path in the magnetic field will have a smaller radius?

An electron and a proton moving with same speed enter the same magnetic field region at right angles to the direction of the field. For which of the two particles will the radius of the circular path be smaller?

A proton having charge e enters a magnetic field of strength B with a velocity v in a direction making angle theta with the direction of the field. The force on proton is

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

A beam of alpha - particles and of protons, of the same velocity v, enters a uniform magnetic field at right angles to the field lines. The aprticles describe

Two identical charged particles moving with same speed enter a region of uniform magnetic field. If one of these enters normal to the field direction and the outer enters along a direction of 30^@ with the field, what would be the ratio of their angular frequencies?

A particle with charge q moving with a velocity v in the plane of the paper enters a uniform magnetc field B, acting perpendicular to the plane of the paper. Deduce an expression for the tie period of the charge, as it moves in a circular path in the field. Why does the kinetic energy of the charge not change, while moving in the magnetic field?

A charge q of mass m moving with velocity v, at right angles to a uniform magnetic field B. Deduce the expression for the radius of the circular path it describes.

A proton and an alpha particle having the same kinetic energy are allowed to pass through a uniform magnetic field perpendicular to the direction of their motion. Compare the radii of the paths of the proton and alpha particle.
