A positive point charge q 1 = +5.00 10 -4 C is held at a fixed

Question:

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 = -3.00 × 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?
