1. Two completely penetrating wells are located L (in metres) apart, in homogeneous confined aquifer. The drawdown measured at the mid point between the two wells (at a distance of 0.5 L from both the wells) is 2.0 m when only the first well is being pumped at the steady rate of Q₁ m³/sec. When both the wells are being pumped at identical steady rate of Q₂ m³/sec, the drawdown measured at the same location is 8, 0 m. It may be assumed that the drawdown at the wells always remains at 10.0 m when being pumped and the radius of influence is larger than 0.5 L Q₁/Q₂ is equal to

B. 4/3
C. 5/8
D. ln (L/2)
