369923 According to Hooke's law of elasticity, if stress is decreased, the ratio of stress to strain

1 Decreases
2 Increases
3 Becomes zero
4 Remains constant
PHXI09:MECHANICAL PROPERTIES OF SOLIDS

369924 Assertion :
When a wire is stretched, some work is done against the internal restoring forces acting between particles of the wire.
Reason :
This work done appears as elastic potential energy in the wire.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.

369925 When the tension in a metal wire is \({T_1}\), its length is \({l_1}\). When the tension is \({T_2},\) its length is \({l_2}\). The natural length of wire is

1 \(T_{1} l_{1}+T_{2} l_{2}\)
2 \(\dfrac{T_{2}}{T_{1}}\left(l_{1}+l_{2}\right)\)
3 \(\dfrac{l_{1} T_{2}+l_{2} T_{1}}{T_{2}+T_{1}}\)
4 \(\dfrac{l_{1} T_{2}-l_{2} T_{1}}{T_{2}-T_{1}}\)

369926 \(A\) and \(B\) are the two wires, the radius of \(A\) is thrice that of \(B\). They are stretched by the same load. Then the stress on \(B\) is

1 Remains same
2 2 times of \(A\)
3 3 times of \(A\)
4 9 times of \(A\)
PHXI09:MECHANICAL PROPERTIES OF SOLIDS

369927 Assertion :
