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 particle of masses in the ration 1:2 with charges in the ratio 1:1, are palced at rest in a uniform electric field. They are relesaded and allowed to move for the same time. The ratio of their kinetic energies will be finally

Two charged particles 'A' and 'B' (with their masses in the ratio of 2:3 and charges in the ratio 1:2 are accelerated from rest through a potential difference V.If a uniform magnetic field (B) is set up perpendicular to their velocities,the ratio of the radii rA:rB of the circular paths described by them will be:

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

When a charged particle of charge x C moves through a potential difference of y V, the gain in kinetic energy is equal to xy J. An electron and an alpha partice have their masses in the ratio of 1:7200 and charges in the ratio of 1:2. If they start moving from rest through the same electrical potential difference, find the ratio of their velocities.
