Two wires are arranged as shown in the figure. The elongations in upper and lower wires are respectively

Text Solution

Verified by Experts


For lower wire `F = m_2g`
` e = (Fl_2)/(Ay_2) rArr e = (m_2gl_2)/(Ay_2)`
For upper wire `F = (m_1+ m_2) g `
` e = (Fl_1)/(Ay_1) rArr e = ((m_1+m_2) gl_1)/(Ay_1)`
