An electron is revolving round a proton, producing a magnetic field of 16 weber/m² in a circular orbit of radius 1 Å. It\'s angular velocity will be

A square conducting loop of side length L carries a current I. The magnetic field at the centre of the loop is

A uniform electric field and a uniform magnetic field are produced, pointing in the same direction. If an electron is projected with its velocity pointing in the same direction

Two particles X and Y having equal charges, after being accelerated through the same potential difference, enter a region of uniform magnetic field and describe circular path of radius R₁ and R₂ respectively. The ratio of mass of X to that of Y is

A charged particle moving in a magnetic field experiences a resultant force

If the direction of the initial velocity of the charged particle is perpendicular to the magnetic field, then the orbit will be
Or
The path executed by a charged particle whose motion is perpendicular to magnetic field is

A 2 MeV proton is moving perpendicular to a uniform magnetic field of 2.5 tesla. The force on the proton is

A uniform magnetic field B is acting from south to north and is of magnitude 1.5 wb/m². If a proton having mass = 1.7 × 10^–27 kg and charge = 1.6 × 10^–19C moves in this field vertically downwards with energy 5 MeV, then the force acting on it will be

The magnetic force on a charged particle moving in the field does not work, because
