A Point Charge of +3 $29.0 \mathrm {~J}$ Of Work to Bring Them to a Final Configuration in Q

Multiple Choice

A point charge of +3.00 μC and a second charge Q are initially very far apart. If it takes $29.0 \mathrm {~J}$ of work to bring them to a final configuration in which the $+ 3.00 - \mu C$ charge is at the point x = 1.00 mm, y = 1.00 mm, and the second charge Q is at the point x = 1.00 mm, y = 3.00 mm, find the magnitude of the charge Q. (k = 1/4πε₀ = 8.99 × 10⁹ N ∙ m²/C²)

A) 2.15 μC
B) 4.30 μC
C) 10.74 μC
D) 4.30 nC
