A charge q is accelerated through a potential difference V . It is then passed normally through a uniform magnetic field , where it moves in a circle of radius r . The potential difference required to move it in a circle of radius 2 r is

A beam of electrons is accelerated through a potential difference V . It is then passed normally through a uniform magnetic field where it moves in a circle of radius r . It would have moved in a circle of radius 2r if it were initially accelarated through a potential difference

A charged particle after being accelerated through a potential difference 'V' enters in a uniform magnetic field and moves in a circle of radius r. If V is the doubled, the radius of the circle will become

A charged particle of mass m and charge q is accelerated through a potential differences of V volts. It enters of uniform magnetic field B which is directed perpendicular to the direction of motion of the particle. The particle will move on a circular path of radius

A charged particle of mass m and charge q is accelerated through a potential differences of V volts. It enters of uniform magnetic field B which is directed perpendicular to the direction of motion of the particle. The particle will move on a circular path of radius

An electron (mass m, charge -e), accelerated through a potential difference V, enters normally a uniform magnetic field B. What will be the radius of the circular motion of the electron ?

A proton is accelerated through a potential difference V, subujected to a uniform magnetic field acting normal to the velocity of the proton. If the potential difference is doubled, how will the radius of the circular path described by the proton in the magnetic field charge ?

A charged particle of mass m and charge q is accelerated through a potential difference of V volts. It enters a region of uniform magnetic field which is directed perpendicular to the direction of motion of the particle. Find the radius of circular path moved by the particle in magnetic field.
