Question: A point particle that has a charge of 25.0 µC is located atx = 0,y = 0 and a point particle that has acharge q islocated at x = 20.0 cm,y =0.The electric force on a point particle that has a chargeof 10.0 µCatx = 40.0 cm,y = 0 is-(19.7) Ni. When this10.0-µC charge isrepositioned atx = 17.8 cm,y= 0, the electric force on it iszero. Determine the chargeq.
My problem: I am unsure how to approach the problem. If I use Coulomb'sLawand set up two different equations and solve for q, thetwoequations produce two different values of q. I don'tunderstand howthe two situations (10.0 µC at (40cm,0)and 10.0 µC at (17.8cm,0))relate to each other.
