Consider a positive charge Q₁ of magnitude 7.5 µC fixed at the origin with another positive charge Q₂ of magnitude 7.5 µC moving near it. Charge Q₂ has a mass of 7 g. Where applicable, let the potential energy be zero when charges are very far apart from each other. Hint a. What is the potential energy of Q2 when it is 3.4 cm from Q₁? PEQ2 = b. If Q2 is released from rest at 3.4 cm from Q₁, how fast is it moving when it reaches 8 cm from Q₁? Hint for (b) VQ2 J. m/s.
