A load of 1kg.wt is attached to one end of a steel wire of area of cross section 3mm^2 and Young's modulus 10^11 N.m^-2. The other end is suspended vertically from a hook on a wall. Then the load is pulled horizontally and released. When the load passes through its lowest position, find the frictional charge in the length of the wire.{take g=10 m.s^-2)

1.	A load of 1kg.wt is attached to one end of a steel wire of area of cross section 3mm^2 and Young's modulus 10^11 N.m^-2. The other end is suspended vertically from a hook on a wall. Then the load is pulled horizontally and released. When the load passes through its lowest position, find the frictional charge in the length of the wire.{take g=10 m.s^-2)
