8th Class Science Force and Pressure Question Bank Force and Pressure

    DIRECTIONS: Read the passage given below and answer the questions that/allow. Passage Pressure is defined as the force exerted over a unit of area. \[\text{Pressure}\,\text{=}\frac{\text{force}}{\text{area}}\] Place a book on a bathroom scale and, whether you place it on its back, on its side, or balanced on a corner, it still exerts the same force. The weight reading is the same. Now balance the book on the palm of your hand and you sense a difference - the pressure of the book depends on the area over which the force is distributed. Which book will exert more pressure?

    A) Book 1            

    B) Book 2

    C) Both exert equal pressure

    D) Can't be determined

    Correct Answer: B

    Solution :

        Pressure \[=\frac{focre}{area}\] Area occupied by book-2 is less than the area occupied by book-1 hence pressure exerted by book-2 > book-1.
