    Optical fiber is the technology associated with data transmission using light pulses travelling along with a long fiber which is usually made of plastic or glass. Metal wires are preferred for transmission in optical fiber communication as signals travel with fewer damages. Optical fibers are also unaffected by electromagnetic interference. The fiber optical cable uses the application of total internal reflection of light.

    By keeping a positively charged sphere near it and hence nearer face gets negatively charged while the farther face gets positively charged. Thereafter remove the positively charged sphere and ground the charge on farther face simultaneously .you will be left with a negatively charged sphere

    Electric field lines cannot cross. If they did, it would mean that the force on a charge at that location would point in two different directions, which does not make any sense at all. Equipotential lines at different potentials can never cross either.

    Rutherford’s Nuclear Model of Atom:b

    • Geiger and Marsden carried out few experiments on the advice of Rutherford
    • On a very thin gold foil, highly energetic ray of α-particles(that are positively charged with energy of 5.5MeV)was incident
    • Scattered α-particles when strike zinc sulphide screen(surrounding the thin gold foil) produced light flashes(scintillations) which were observed via detector(microscope)
    • Electrons and protons are bound together by electrostatic forces of attraction and atom, as a whole is electrically neutral.
    • Rutherford was the first to discover that atom has a nucleus and so his model was called as Rutherford’s nuclear model of atom.
