    Thank you for downloading this booklet on Test papers for class XII in physics. The

    idea of this booklet is mainly to make the readers to go through the NCERT Text book.

    Before answering this test series please go through the chapter in the NCERT text book

    and then proceed to answer the test papers related to that chapter. Answer to each

    question can be obtained from the text book itself. The advantage of this booklet is

    that the page number in which the answer to that particular question can be obtained

    is shown against the question itself.

    These test papers can be used to evaluate one’s performance with respect to a particular

    chapter. If the student evaluates himself one will come to know what type of questions

    will be given for 1 mark, 2 marks & 3 marks and how much time each question takes

    to answer and what type of preparation one requires.

    My sincere thanks to those sites from which I have downloaded the images/material

    from the internet.

    Please don’t forget to give your feedback to the following address [email protected]

    or [email protected]

    5cm

    A metallic sphere A is suspended by a nylon thread. Another charged metallic sphere

    B held by an insulating handle is brought closed to A such that the distance between

    their centres is 10 cm.The resulting repulsion of A is noted. Spheres A and B are

    touched by uncharged spheres C and D respectively, as shown in fig. C and D are

    3
