Two Equally Charged Tiny Spheres of Mass $1.0 \mathrm {~g}$ Are Placed

question 81

Multiple Choice

Two equally charged tiny spheres of mass $1.0 \mathrm {~g}$ are placed $2.0 \mathrm {~cm}$ apart. When released, they begin to accelerate away from each other at $414 \mathrm {~m} / \mathrm { s } ^ { 2 }$ . What is the magnitude of the charge on each sphere, assuming only that the electric force is present? $\left( k = 1 / 4 \pi \varepsilon _ { 0 } = 9.0 \times 10 ^ { 9 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { C } ^ { 2 } \right)$

• A) \(140 \mathrm { nC }\)
• B) \(95 \mathrm { nC }\)
• C) \(120 \mathrm { nC }\)
• D) \(75 \mathrm { nC }\)
