Two charged particles have charges and masses in the ratio `2:3` and `1:4` respectively. If they enter a uniform magnetic field and move with the same velocity then the ratio of their respective time periods of revolutions is

A proton and an alpha particle enter in a uniform magnetic field with the same velocity. The time period of rotation of the alpha particle wil be

Two charged particle having masses in the ratio 2:3 and charges in the ratio 1:2 are released from rest in a uniform electric field.After a time 1 minute their K.E.will be in the ratio of

Two charged particles having masses in the ratio 2: 3 and charges in the ratio 1: 2 are released from rest in a uniform electric field. After a time 1 minute their K.E. will be in the ratio of

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

A charged particle enters a uniform magnetic field perpendicular to it. The magnetic field
