    Wires A and B are made from the samematerial. A has twice the diameter and threetimes the length of B. If the elastic limits arenot reached, when each is stretched by thesame tension, the ratio of energy stored in Ato that in B is

    A)  2 : 3                                      

    B)  3 : 4

    C)  3 : 2                                      

    D)  6 :1

    Correct Answer: B

    Solution :

                                   \[\frac{3.08}{\sqrt{T}}\overset{0}{\mathop{A}}\,\] \[\frac{0.308}{\sqrt{T}}\overset{0}{\mathop{A}}\,\] \[\frac{0.0308}{\sqrt{T}}\overset{0}{\mathop{A}}\,\] (F and Y are constant)                 \[{{E}_{e}}\]       \[{{E}_{ph}}\]                                 \[\frac{{{E}_{e}}}{{{E}_{ph}}}\]
