Two identical positive point charges Q are initially spaced a distance d apart. If they are released from test, how fast will they be moving when they are very far away from each other? Assume they have identical masses m, and express your answer in terms of the given quantities and the Coulomb constant k. 'Consider one of the point charges Q to be in the electric potential Vof the other one, so the potential energy is initially QV. 'Use energy conservation. What is the potential energy when the charges are very (innitely) far apart? 'Recall that kinetic energy is given by XE : If: m v2. Both charged objects end up with increased kinetic energy. Evaluate the speed numerically if Q = 0.77 p13,: = 1.13 mg. and a' = 5.1 cm
