Two point charges are located on the x-axis of a coordinate system: 𝑞_1 =-1.5 𝑛𝐶 is at 𝑥 = +4.0 𝑐𝑚, and 𝑞_2=−3.5 𝑛𝐶 is at 𝑥 = +2.0 𝑐𝑚. What is the total electric force exerted by 𝑞_1 and 𝑞_2 on a 𝑞_3= 2.0 𝑛𝐶 at 𝑥 = +3 cm?

A city when its operation is normal uses a supply of drinking water
containing 15 mg /L of chloride (Cl-), but during periods of high water demand,
mixes with groundwater containing 65 mg/L Cl-. The two waters mix
completely in a 1400 m3 tank and then sent to the distribution system. the
demand for many days has been ~500 m3/d, and all the water has come from
the main supply. So, the demand increases to 700 m3 /d, and the additional
200 m3/d is extracted from the groundwater supply. How long can
continue with this operating strategy before the water entering the
distribution system contains ≥ 20 mg/L Cl-? (Note: chloride is not reactive).
