WHAT IS THE COULOMB'S LAW

THE COULOMB'S LAW IS Between 1785 and 1787, the French physicist Charles Augustine de Coulomb performed a series of experiments involving electric charges, and eventually established what is nowadays known as Coulomb's law. According to this law, the force acting between two electric charges is radial, inverse-square, and proportional to the product of the charges. Two like charges repel one another, whereas two unlike charges attract. Suppose that two charges, $q_1$ and $q_2$, are located at position vectors ${\bf r}_1$ and ${\bf r}_2$. The electrical force acting on the second charge is written 

\begin{displaymath} {\bf f}_2 = \frac{q_1 q_2}{4\pi \epsilon_0} \frac{{\bf r}_2 - {\bf r}_1} {\vert{\bf r}_2-{\bf r}_1\vert^{3}} \end{displaymath}


in vector notation . An equal and opposite force acts on the first charge, in accordance with Newton's third law of motion. The SI unit of electric charge is the coulomb (C). The magnitude of the charge on an electron is $1.6022\times 10^{-19}$ C. The universal constant $\epsilon_0$ is called the permittivity of free space, and takes the value 
\begin{displaymath} \epsilon_0 = 8.8542\times 10^{-12} {\rm C^{ 2} N^{-1}m^{-2}}. \end{displaymath}

    AAKASH TBLET

    THE INFERMATION OBUT THE AAKASH TABLET
    The Aakash tablet is the world’s cheapest computing device. It is ideal for use by students at whom the machine is actually targeted. The design of the tablet has been maintained simple and basic; but is a little bulkier when compared to the other similar devices


    The high point of the Aakash Tablet is its competitive price which is within means of the masses. The tablet was developed keeping in mind the general public in India, especially the student community spread out in far flung places. The tablet was developed under the aegis of Shri.Kapil Sibal

    The tablet that made headlines across the world as being an innovative computing device is developed with big goals towards improving the education standard even in rural townships. The (NME-ICT) National Mission on Education through Information and Communication Technology has plans of linking Universities and Colleges across the country so the students can benefit from a higher standard of education. It is proposed that a total of 416 Universities and 20,000 colleges in the country will be initially linked through this system. NME-ICT proposes at least 18 separate line items for the benefit of content creation
