A 70-?C Point Charge and A A 9.0 $9.0 - \mu \mathrm { C }$

question 15

Multiple Choice

A 7.0-?C point charge and a $9.0 - \mu \mathrm { C }$ point charge are initially extremely far apart. How much work does it take to bring the $7.0 - \mu \mathrm { C }$ point charge to the point $x = 3.0 \mathrm {~mm} ,$ $y = 0.0 \mathrm {~mm}$ , and the $9.0 - \mu \mathrm { C }$ point charge to the point $x = - 3.0 \mathrm {~mm} ,$ $y = 0.0 \mathrm {~mm} ?$ (k = 1/4??₀ = 9.0 × 10⁹ N ? m²/C²)
