A 30-m steel tape weighing 1.45 kg is of standard lengthunder a pull of 5 kg, supported for full length. The tapewas used in measuring a line 938.55 m long on smoothlevel ground under a steady pull of 10 kg. Assuming E =6.22.0 x10° kg/cm and the unit weight of steel to be 7.9 x1033kg/cm, determine the correct length of the linemeasured.а.948.1 mb. 938.59 mС.950 m
