Question

The closest star to the Sun is Alpha Centauri. Alpha Centauri is about 4.12 × 1016 meters away from the Sun. The mass of the Sun is approximately 2.00 × 1030 kilograms. The mass of Alpha Centauri is slightly greater than this, at 2.19 × 1030 kilograms. What is the magnitude of the gravitational force of attraction between these two stars?

Answer 1

Answer:

Alpha Centauri is the third-brightest star in our night sky – a famous southern star – and the nearest star system to our sun. Through a small telescope, the single star we see as Alpha Centauri resolves into a double star. This pair is just 4.37 light-years away from us. In orbit around them is Proxima Centauri, too faint to be visible to the unaided eye. At a distance of 4.25 light years, Proxima is the closest-known star to our solar system.

Answer 2

Answer 1.72x10^30

Explanation:

Use the mathematical formula for gravitational force is F=GMm/r2

F = G Mm/r 2 where G is the gravitational constant of 6.67x10^-11

plug the values in

F= (6.67x10^-11) (2.00 × 10^30)(2.19 × 10^30) / (4.12 × 10^16)2

F= 1.72x10^30
