Question

2 particles are moving with constant speed v such that they are always at a constant distance d apart and their velocities are equal and opposite. After what time will they return to their initial positions

Answer 1

Answer:Total distance /velocity

Explanation:Two particles are moving with constant speed "v" and they are always at a constant distance. This is possible only when the particles move in a circular path wrt to each other. Time taken to return to their initial positions = Total distance /velocity
