  • The collector plate in an experiment on photo electric effect is kept vertically above the emitter plate. Light source is put on and a saturation photo current is recorded. Parallel electric and magnetic fields are applied vertically downwards between the plates. Then

    A
    The photo current will increase
    B
    The K.E. of the photo electron will decrease
    C
    The stopping potential will increase
    D
    The threshold wave length increases
  • A non mono chromatic light is used in an experiment on photo electric effect. The stopping potential is related to the

    A
    Mean wave length
    B
    Longest wave length
    C
    Shortest wave length
    D
    Distance of the source from the metal
  • Physicists firmly believe that all forces operating in nature are, in fact, different aspects of a single force, the so called “super-force' and it is in this context that : a) Newton united terrestrial gravitation (TG) and astronomical gravitation (AG) into single Gravitational Interaction (GI) b) Hans Oersted and Michael Faraday demonstrated that electric interaction (EI) and magnetic interactions (MI) wre interlinked. Subsequently, these interactions were unified into a single interaction, called Electromagnetic Interaction (EMI) by Clerk Maxwell. c) In 1920, Einstein tried to prove that gravitational interaction and electromagnetic interactions were the same, but he never succeeded. Where Einstein and other great scientists of the last century failed, their successors successfully combined weak interaction (WI) with electromagnetic interaction (EI) into a single Electro Weak Interaction (EWI). d) Grand Unification Theories (GUIS) are being actively pursued to unify strong interaction (SI) with electro weak interaction into so called Grand Unified Interaction (GUI). e) And finally, theories of Everything (TOE) are attempting to unify gravitational interaction with GUI into that elusive superforce, called Universal Interaction (UI). The various interactions operating in nature have been represented in figure Here, straight arrows represent what has been accomplished so far and the dotted arrows represent what is being pursued towards the unification of these interactions. The grand unification theory as diagram is hopefully a combination of

    A
    SI and EWI only
    B
    SI and WI only
    C
    SI and EWI only
    D
    GI and GUI

    What is the relation between the amplitudes of the electric and magnetic fields in free space for an electromagnetic wave ?

    Magnetic field due to a long current-carrying wire Oersted's experiments showed that there is a magnetic field around a current-carrying wire. We determine the magnitude of magnetic field at some distance from a long stright wire carrying a current I.
