A positive point charge q1 = +5.00×10−4 C is held at a fixed position. A small object with mass 4.00×10−3 kg and charge q2 = −5.00×10−4 C is projected directly at q1. Ignore gravity. When q2 is 0.400 m away, its speed is 800 m/s. What is its speed when it is 0.200 m from q1? Express your answer with the appropriate units.

9. Object #1 has mass m; object #2 has mass 10m. They are separated by the distance d. We can conclude that: Object 1 exerts greater gravitational force on object 2, than object 2 exerts on 1. Object 1 exerts smaller gravitational force on object 2, than object 2 exerts on 1. Object 1 exerts on object 2 gravitational force equal in magnitude to force eqerted by 2 on 1. Our answer depends on distance d. 10. Consider two objects:...
