Motion of a Charged Particle in a Uniform Magnetic Field : Class12 Physics


 PHYSICS
CLASS-12
CBSE/ICSE/IB BOARD/BSEB(BIHAR BOARD)/IIT-JEE/NEET
LECTURE-12
CHAPTER: MAGNETIC EFFECT OF CURRENT
MOTION OF A CHARGED PARTICLE IN A UNIFORM MAGNETIC FIELD :
Motion of a charged particle in a uniform magnetic field
1. Lorentz magnetic force
2.Trajectory of charged particle                                                                                                  3.Three cases arise :
(a)when charged particle is moving along the direction of magnetic field i.e. angle between velocity and magnetic field is zero
(i) Expression for Lorentz force
(ii)Trajectory of particle
  (b)When charged particle is moving perpendicular to the direction of magnetic field 
        i.e. the angle between velocity and magnetic field is 90 degree
         (i) Trajectory of particle
          (ii)Expression for Lorentz force
           (iii)Expression for centripetal force
           (iv)Expression for radius
            (v)Expression for velocity
            (vi)Expression for angular frequency/angular velocity
            (vii)Expression for frequency
            (viii)Expression for time period
            (ix)Expression for kinetic energy
(c)When the angle between velocity of charged particle and magnetic field < 90 degree
   (i) Trajectory of particle
          (ii)Expression for Lorentz force
           (iii)Expression for centripetal force
           (iv)Expression for radius
            (v)Expression for velocity
            (vi)Expression for angular frequency/angular velocity
            (vii)Expression for frequency
            (viii)Expression for time period
            (ix)Expression for kinetic energy

    I have been publishing a set of the most important topics since 8 Jan.2021 for students of class-12 Physics preparing for CBSE BOARD/ICSE BOARD/BSEB( BIHAR BOARD )/IIT-JEE/NEET .It is one of them. Compare my lecture with other. If it is better than other ,learn it and score marks -5/5.
    Thank you

Dual Nature of Matter and Radiation Class 12 Physics

                                                                                                                                                    Dual Nature of Matter and Radiation Introduction The discovery of phenomena like interference, diffraction and polarization established that wave of nature. Maxwell’s equations of electromagnetism and Hertz experiment on production and detection of electromagnetic waves in 1886 strongly supported the concept of wave nature of light . The discovery of cathode rays by William Crookes in 1879, of X-rays by Roentgen in 1895 and of electrons by J.J. Thomson in 1897 were very importan...

Light | Reflection of Light | Laws of reflection | Classs 10 physics

Light | Reflection of Light | Laws of reflection | Classs 10 physics Here we study class 10 physics,optics,light,reflection of light,laws of reflection,plane mirror,reflection by plane mirror,theory of light. Light 1. Light is a form of energy which enables us to see an object. 2.It is an electromagnetic wave. 3.Light waves are transverse in nature. 4.Light waves are electromagnetic radiation so they do not need a material medium to  travel. 5.It travels in vacuum as well as in material transparent medium. 6. The speed of light is 300000km/s in vacuum. 7.The speed of light in material medium is less than in vacuum. 8. Light travels in a  straight line. 9.Light is the fastest messenger in the universe. Theory of Light There are four theories of light. These are 1 . Newton's Corpus cular Theory of Light  : It explains corpuscles/particles nature of light.It proves rectillinear propagation of light, Reflection of light,Refraction of light. It does not prove interference of ...

Hertz, Hallwacks and Lenards's Observations on Photoelectric Effect

  Hertz, Hallwacks and Lenard's observation on Photoelectric effect Hertz observation The phenomenon of photoelectric emission was discovered by Heinrich Hertz in 1887, when he was working with his electromagnetic wave experiment. When suitable radiations fall on a metal surface,some electrons near the surface observe enough energy from the incident radiation. Due to it, they are able to overcome the attraction of the positive ions in the material of the surface and escape to the surrounding space. Hallwacks and Lenard’s observation Hallwack and Lenard made a detailed study of the Photoelectric effect during 1886 to 1902. They observed,” when ultraviolet radiation falls on an emitter plate that is positive plate electrons are emitted from it which are attracted towards the other metal plate called collector plate kept at positive potential.The flow of electrons through the evacuated glass tube results in the current flow in the external circuit.  Thus light falling on the surf...
