What is the number of electric field lines coming out from a 0.885 C charge?

Coulomb's law for the magnitude of the force F𝐹 between two particles with charges  Q𝑄 and  Q′𝑄′ separated by a distance d𝑑 is|F|=K|QQ′|d2|𝐹|=𝐾|𝑄𝑄′|𝑑2,where K=14πϵ0𝐾=14𝜋𝜖0, and ϵ0=8.854×10−12C2/(N⋅m2)𝜖0=8.854×10−12C2/(N⋅m2) is the permittivity of free space.Consider two point charges located on the x axis: one charge, q1𝑞1 = -19.5 nCnC , is located at x1𝑥1 = -1.690 mm ; the second charge, q2𝑞2 = 31.0 nCnC , is at the origin (x𝑥 = 0).Part AWhat is (Fnet3)x(𝐹net3)𝑥 , the x-component of the net force exerted by these two charges on a third charge q3𝑞3 = 48.5 nCnC placed between  q1𝑞1 and  q2𝑞2 at x3𝑥3 = -1.185 mm ?Your answer may be positive or negative, depending on the direction of the force.Express your answer numerically in newtons to three significant figures.View Available Hint(s)
