Stars are held together by a. ionic forces. c. electrical forces. b. magnetic forces. d. gravitational forces. select the best answer from the choices provided a b c d

d. gravitational forces

Explanation:

Stars are far apart and the force between the stars are given as gravitational force between them which is given as

here we know that

= mass of star 1

= mass of star 2

here since two stars are far apart so there is no possibility of electromagnetic force as well as there is no possibility of nuclear force between the stars

So here all stars are bounded together by gravitational attraction force between them so correct answer will be

d. gravitational forces
