The value of force constant between the applied elastic force $F$ and displacement will be
$\sqrt 3 $
$\frac{1}{{\sqrt 3 }}$
$\frac{1}{2}$
$\frac{{\sqrt 3 }}{2}$
The adjacent graph shows the extension $(\Delta l)$ of a wire of length $1m$ suspended from the top of a roof at one end with a load $W$ connected to the other end. If the cross sectional area of the wire is ${10^{ - 6}}{m^2},$ calculate the young’s modulus of the material of the wire
The graph shows the behaviour of a length of wire in the region for which the substance obeys Hook’s law. $P$ and $Q$ represent
In the below graph, point $D$ indicates
The stress versus strain graphs for wires of two materials $A$ and $B$ are as shown in the figure. If ${Y_A}$ and ${Y_B}$ are the Young ‘s modulii of the materials, then
In the below graph, point $B$ indicates
