A deuteron and an alpha particle having same momentum are in turn allowed to pass through a magnetic field B, acting normal to the direction of motion of the particles. Calculate the ratio of the radii of the circular paths described by them.

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.

A proton and an alpha particle of the same velocity enter in turn a region of unifrom magnetic field acting a plane perpendicular to the magnetic field. Deduce the ratio of the radii of the circular paths described by the particles. Explain why kinetic energy of the particle after emerging from the magnetic field remains unaltered.

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 and an alpha -particle enter a uniform magnetic field perpendicularly with the same speed. How many times if the time period of alpha -particle than that of proton? Deduce the expression for the ratio of the radii of the circular paths of two particles.

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

A neutron, a proton, an electron and an alpha particle enter a region of constant magnetic field with equal velocities. The magnetic field is along the inward normal to the plane of paper. The tracks of the particles are labelled in Fig. SAQ 11. which of the tracks show the path of the electron and alpha-particles ?

An electron after bein accelerated through a potential difference of 1 00 V enters a uniform magnetic field of 0.004 T perpendiular to its direction of motion. Calculate the radius of the path describe by the electron. Given m = 9.1 xx 10^-31 kg and e = 1.6 xx 10^-19 C
