JEE MainPhysicsCurrent ElectricityMCQ+4 / −1
A 1 m1 \mathrm{~m}1 m long wire is broken into two unequal parts X\mathrm{X}X and Y\mathrm{Y}Y. The X\mathrm{X}X part of the wire is streched into another wire W. Length of WWW is twice the length of XXX and the resistance of W\mathrm{W}W is twice that of Y\mathrm{Y}Y. Find the ratio of length of X\mathrm{X}X and Y\mathrm{Y}Y.
