Gravitational pull on an object

  1. Jan 31, 2014 #1
    How much does gravitational pull on an object decrease if the distance is increased 10 fold for example?

    If planet x is stationary and part of a binary star system where star y is 1 AU away from it and star z is 1,000 AU's away, but also has 1,0000 times the mass, which star will exert more gravitational pull on planet x?

    use the gravitation formula and notice that its inversely proportional to the square of the distance. so 10 fold increase means 100 fold decrease
