Question

The largest fountain is found at Fountain Hills Arizona , Under ideal conditions the 8000 kg column of water can reach as high as 190m. Suppose a 12nC charge is placed on teh ground and another charge of unknown quantity is located 190m above the first charge. At a point on the ground 120m from the first charge, the horizontal component of the resultant electric field strength is found to be Ex=1.6x10^-2 N/C. Using this information calculate the unknown quantity of charge
