369943 Two blocks of masses \(m\) and \(M\) are connected by means of a metal wire of cross-sectional area shown in the figure. The system is then released. If \(M = 2\;m,\) then the stress produced in the wire is :

369944 In the figure (i) an extensible string is fixed at one end and the other end is pulled by a force \(F\). In figure (ii) another identical string is pulled by force ' \(F\)' at both the ends. The ratio of elongation in equilibrium of string in (i) to the elongation of string in (ii) is

369945 Assertion :
Strain is a unitless quantity.
Reason :
Strain is equivalent to force.

369946 The length of a wire increases by \(2 \%\) by a load of \(5\;kg - wt\). The linear strain produced in the wire will be
