Question

A.) Two identical 43 mg dust particles very far apart (PE_E ≈ 0) are moving directly toward each other at a speed of 9633 m/s. The charge on each is 540 ?C. Find how close they will get to each other. Let k = 9×10⁹ N·m²/C² & ignore gravity.

B.) Two identical 31 mg dust particles 6.1 m apart are released from rest. The charge on each is 606 ?C . Find how fast they will be going when they are an infinite distance apart. Let k = 9×10⁹ N·m²/C² & ignore gravity.
