A Tiny Object Carrying a Charge of +3

question 55

Multiple Choice

A tiny object carrying a charge of +3.00 μC and a second tiny charged object are initially very far apart. If it takes 29.0 J of work to bring them to a final configuration in which the +3.00 μC object i is at x = 1.00 mm, y = 1.00 mm, and the other charged object is at x = 1.00 mm, y = 3.00 mm, find the magnitude of the charge on the second object. (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
