This paper contains important questions from the complete syllabus of CBSE Class 11 Physics

    Few sample questions from the Question Paper are given below:

    Q. Manoj is a civil engineer by profession. One day, he visited to his native village. He noticed a high mountain made up of rock in his locality. He thought that if he somehow removes it then the land can be used for various useful purposes. He took permission from the government and completed all the formalities. He broke the mountain parts by parts with the help of dynamite. Small pieces of rocks from the mountain are used for construction purposes. He also establishes a wheat flour mill on this land. Many of the people in the surroundings started to earn and live comfortably.
    (a) What values of Manoj impress you?
    (b) A rock in the state of rest on the land explodes into two parts of masses 6 Kg and 3 Kg. the heavier fragment to move in the horizontal direction with a velocity of 80 m/s .Calculate the speed and direction of the lighter fragment.
