1.
An electron and a proton of equal linear momentum enter in the direction perpendicular to uniform magnetic field. If the radii of their circular paths be 
respectively, then 
is equal to 
mass of electron, 
mass of proton.
respectively, then is equal to mass of electron, mass of proton.
2.
An electron of mass 
and charge 
is travalling with a speed 
along a circular path of radius 
at right angles to a uniform of magnetic field 
If speed of the electron is doubled and the magnetic field is halved, then resulting path would have a radius of

3.
A charged particle enters in a magnetic field whose direction is parallel to velocity of the particle, then the speed of this particle
4.
Two circular concentric loops of radii 
are placed in the 
plane as shown in the figure. A current 
is flowing through them. The magnetic moment of this loop system is

5.
A charged particle is moving in a magnetic field of strength 
perpendicular to the direction of the field. If 
denote the charge and mass of the particle respectively, then the frequency of rotation of the particle is
perpendicular to the direction of the field. If denote the charge and mass of the particle respectively, then the frequency of rotation of the particle is
