A distribution feeder of 1 km length having resistance, but negligible reactance, is fed from both the ends by 400 V, 50 Hz balanced sources. Both voltage sources S 1 and S 2 are in phase. The feeder supplies concentrated loads of unity power factor as shown in the figure. The contributions of S 1 and S 2 in 100 A current supplied at location P respectively, are

Correct Answer is : 0 A and 100 A
