The gravitational force between two objects is 2000 n. the mass of each object is reduced to one-third of its original mass.
how must the distance between the objects change to keep the gravitational force between them 2000 n?
the distance must be one-ninth the original distance.
the distance must be one-third the original distance.
the distance must be three times greater.
the distance must be nine times greater.

This would suggest that the distance have changed from the original distance which is 1/3.I believe the closest possible answer to this question is The distance must be one-third the original distance.

Thank you for your question. Please don't hesitate to ask in your queries. 

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. the winds blow from west to east in jet streams but the flow often shifts to the north and south. jet streams follow the boundaries between hot and cold air. the earth's rotation is responsible for the jet stream as well.
