Question

Two objects with massesof 1.0 kg and 2.0 kg are 1.0 m apart. the magnitude of the gravitational force between these masses is 1.33 x 10 ^-10 NIf the distance between the two masses weretripled, by what factor would the mutual gravitation force changed?

Answer 1

Given

Object 1

m = 1kg

Object 2

m = 2 kg

Gravitational force

Fg = 1.33 x 10^-10 N

Procedure

Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers

As the distance is tripled the gravitational force would change by a factor of 1/9
