If the tension on a wire is removed at once, then
It will break
Its temperature will reduce
There will be no change in its temperature
Its temperature increases
Two wires of the same material (Young's modulus $Y$ ) and same length $L$ but radii $R$ and $2R$ respectively are joined end to end and a weight $W$ is suspended from the combination as shown in the figure. The elastic potential energy in the system is
The ratio of Young's modulus of the material of two wires is $2 : 3.$ If the same stress is applied on both, then the ratio of elastic energy per unit volume will be
A wire of length $L$ and cross-sectional area $A$ is made of a material of Young's modulus $Y.$ It is stretched by an amount $x$. The work done is
Does the energy stored in a spring changes when it stretched or compressed ?
On stretching a wire, the elastic energy stored per unit volume is
