Two planets of the same mass are observed.


Which of the following distances between the two planets would result in the least gravitational attraction?

A90 light years
B80 light years
C60 light years
D50 light years

Verified Answer :

AL2006

It really doesn't matter what mass the planets have, or whether they're equal, or whether they're planets. The farther apart two objects are, the less gravitational attraction there is between them.

As the distance increases, the gravitational force between them decreases.
So, the option with the largest distance is (A) 90 light yrs. And that's the answer !!
