An alpha particle and a proton on entering a magnetic field are found to travel along the same circular path. Then their kinetic energies are in the ratio

A charged particle (+q) enters into a uniform magnetic field region of induction B and desribes a circle. The kinetic energy of the charged particle is

A charged particle enters at 60^@ to the magnetic field: The path of the charged particle

A charged particle enters at 90^@ to a unifrm magnetic field. The locus of its trajectory will be

Two charged particles carrying equal charge enter into a magnetic field region after being accelerated through the same potential difference. The particles describe circular paths of radii R_1 and R_2 respectively. If m_1 and m_2 are the masses of the particles then ((m_1)/m_2) is given by

When will the angular and linear velocity of the particle moving in a circular path be the same ?

The magnetic field induction at a long distance from a short bar magnet along axial and equatorial positions are in the ratio

An electron of mass (m_e) and a proton of mass (m_p=1836m_e) are accelerated to move from one point to another in an electric field of potential difference of 1 Volt. The gain in kinetic energies of the electron and proton respectively are
