A load of 20kg is suspended by a steel wire in a sonometer experiment. Velocity of waves when the wire is rubbed with a resined cloth along the length is 20 times the velocity of waves in the same string, when it is plucked. Find area of cross-section of the wire, if Y for steel is `19.6xx10^(10)N//m^(2) and g =9.8m//s^(2)`.
