  • Question 1
    4 / -1

    The stress versus strain graphs for wires of two materials A and B are as shown in the figure. If YA and YB are the Young\'s modulii of the materials, then

  • Question 2
    4 / -1

    The load versus elongation graph for four wires of the same material is shown in the figure. The thickest wire is represented by the line

  • Question 3
    4 / -1

    The graph is drawn between the applied force F and the strain (x) for a thin uniform wire. The wire behaves as a liquid in the part

  • Question 4
    4 / -1

    The graph shows the behaviour of a length of wire in the region for which the substance obeys Hooke\'s law. P and Q represent

  • Question 5
    4 / -1

    The potential energy U between two molecules as a function of the distance X between them has been shown in the figure. The two molecules are

  • Question 6
    4 / -1

    The value of force constant between the applied elastic force F and displacement will be Y

  • Question 7
    4 / -1

    Which one of the following is the Young\'s modulus (in N/m2) for the wire having the stress-strain curve shown in the figure?

  • Question 8
    4 / -1

    The diagram shows the change x in the length of a thin uniform wire caused by the application of stress F at two different temperatures T1 and T2. The variations shown suggest

  • Question 9
    4 / -1

    A student plots a graph from his reading on the determination of Young\'s modulus of a metal wire but forgets to label. The quantities on X and Y axes may be respectively.

  • Question 10
    4 / -1

    The points of maximum and minimum attraction in the curve between potential u energy (U) and distance diatomic are
