In a moving cell galvanometer, we use a radial magnetic field so that the galvanometer scale is

A proton enters a perpendicular magnetic field of 20 Tesla. If the velocity of proton is $$4 \times 10^7 m/s$$ then the force acting on it will be :

An electron moving to the east in a horizontal plane is deflected towards south by a magnetic field. The direction of this magnetic field is

A charge q is moving with a velocity v parallel to a magnetic field B. Force on the charge due to magnetic field is

The path of a charged particle moving in a uniform steady magnetic field cannot be a :

A conducting rod AB moves parallel to X-axis in a uniform magnetic field, pointing in the positive X-direction. The end A of the rod gets
