Magnetic Effect...

A proton, a deutron and an a-particle are accelerated through same potential difference and then they enter a normal uniform magnetic field. The ratio of their kinetic energies will be-

A proton of energy 8eV is moving in a circular path in a uniform magnetic field. The energy of an a-particle moving in the same magnetic field and along the same path will be-

An electron is revolving in a circular path of radius 2×10^–10 m with a speed of 3×10⁶ m/s. The magnetic field at the centre of circular path will be-

An a particle travels at an angle of 30º to a magnetic field 0.8 T with a velocity of 10⁵ m/s. The magnitude of force will be-

A beam of protons is moving horizontally towards you. As it approaches, it passes through a magnetic field directed downward. The beam deflects-

If a particle moves in a circular path in clockwise direction after entering into a downward vertical magnetic field. The charge on the particle is-

In the example above, after how much time, particle comes to the starting point for the first time. (mass of particle = m)

A current of 2.0 amp is flowing through a wire of length 50 cm. If this wire be placed at an angle of 60º with the direction of a uniform magnetic field of 5.0 × 10^–4 N/Am the force on the wire will be

A particle of mass m and charge q moves with a constant velocity v along the positive x direction. It enters a region containing a uniform magnetic field B directed along the negative z direction, extending from x = a to x = b. The minimum value of v required so that the particle can just enter the region x > b is

A particle with charge Q, moving with a momentum p, enters a uniform magnetic field normally. The magnetic field has magnitude B and is confined to a region of width d, where d < p/BQ.The particle is deflected by an angle θ in crossing the field.
