    Electrostate Assignment-1 for the class 12

    These questions are based on the 12th Board examination. This first set of questions cover the chapters of Electrostatic in Physics where we deal with charge in rest and what properties it shows. Check the questions below of electrostate Assignment-1 for the class 12 .

    Short answer type Questions

    Q1. Can a charged body attract an uncharged body?

    Q2. A small test charge is released at rest at a point in an electrostatic field. Will it travel along the field line passing through that point?

    Q3. In an electric field an electron is kept freely. If the electron is replaced by proton, what will be the relationship between the forces experienced by them?

    Q4. A metallic sphere is placed in uniform electric field as shown in the figure. Which path is followed by electric field lines and why?

    Q5. find the value of electric field that would exactly balance the weight of electron.

    Q6. if the Coulomb’s law involved 1/r3 dependence (instead of 1/r3), where r is distance between two point changes would Gauss’s law still be true?

    Q7. A glass rod is rubbed with silk. Will its mass increase or decrease ?

    Q8 . An electrostatic field line cannot be discontinuous, why?

    Q9. Which orientation of an electric dipole in a uniform electric field would correspond to stable equilibrium ?

    Q10. The distance of the point on equatorial plane of a small electric dipole is halved. By what factor will the electric field due to dipole at the point changes?

    Q11. When two electrically charged particles having charges of different magnitude are placed at a distance d from each other, they experience a force of attraction F. these two particles are put in contact and again placed at the same distance from each other. What is the nature of new forces between them ?

    Q13. Repulsion is the sure test of electric charge. Explain

    Q14. An electric dipole moment P is placed in a uniform electrostatic field E. for what angle between P and E will the potential energy of the electric dipole be half of its maximum value?

    Q15. Figure shows three point charges +2q , -q and +3q. two charges +2q and –q are enclosed within a surface S. what is the electric fix due to this configuration through the surface S?

    What is Lorem Ipsum?

    Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

    Why do we use it?

    It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

    Where does it come from?

    Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of “de Finibus Bonorum et Malorum” (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, “Lorem ipsum dolor sit amet..”, comes from a line in section 1.10.32.
