When a load of 10 kg is hung from the wire, then extension of 2m is produced. Then work done by restoring force is

Assertion : A wire of uniform cross-section and uniform resistivity is connected across an ideal cell. Now the length or wire is doubled keeping volume of wire constant. The drift velocity of electrons after stretching the wire becomes one fourth of what it was before streching the wire. Reason: If a wire (or uniform resistivity and uniform cross-section) of length l_(0) is stretched by a factor n, then its resistance becomes n^(2) times the one before stretching the wire (the volume of wire is kept constant in stretching process.) Fruther at constant potential difference, current is inversely proportional to resistance. Drift velocity of free electron is directly proportional to current and inversely proportional to cross-sectional area of current carrying wire.
