Two identical planets, each with a mass of 1024 kg, orbit around the midpoint between the two planets. If the distance between the two planets is 2 x 108 m (as measured from their centers), how fast is each of the planets moving in their orbit?

each of the planets moving  = 408.35 m/s

Explanation:

given data

mass =   kg

distance between two planets = 2 × m

solution

if distance between two planet is 2 × m it mean it's diameter so

that radius will be 1 × m

and

F =    ................1

and

F =   ..............2

so from equation 1 and 2 will be

=    

v =     ............2

put here value

v =    

v = 408.35 m/s

measure their densities same density, same sub
