Given two particles with Q = 2.70-µC charges as shown in the figure below and a particle with charge q = 1.29 ✕ 10⁻¹⁸ C at the origin. (Note: Assume a reference level of potential V = 0 at r = ∞.)

(a)What is the net force (in N) exerted by the two 2.70-µC charges on the charge q? (Enter the magnitude.)

N

(b)What is the electric field (in N/C) at the origin due to the two 2.70-µC particles? (Enter the magnitude.)

N/C

(c)What is the electrical potential (in kV) at the origin due to the two 2.70-µC particles?

kV

(d)What If? What would be the change in electric potential energy (in J) of the system if the charge q were moved a distance d = 0.400 m closer to either of the 2.70-µC particles?
