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

    this is tricky. In my opinion, two object moving at the same and opposite direction means that both object traveled from a different point of origin. So if we have these objects stuck together because of the constant d, then i guess neither of the object will make it to the initial position.

    in short, both object cannot get to the initial position.

    The time should be 2πr/v

  • science -

    The time should be 2πr/v...as both the particles are at a constant distance d...therefore for one particle-
    Distance covered =circumference
    Velocity =v
    Therefore..t=2πr/v
