Two identical spheres of equal mass a distance of 10 m apart a surface gravity of 0.0050 to each other where are the masses

The masses of the two identical spheres are, M = 1.47 x 10¹³ kg  

Explanation:

Given data,

The distance of separation of to identical spheres, d = 10 m

The first sphere exerts a surface gravity on the second sphere is, g = 0.0050 m/s²

The second sphere exerts a surface gravity on the first sphere is, g = 0.0050 m/s²

The formula for surface gravity is,

                           g = GM/d²

∴                          M = gd²/ G

Substituting the values

                            M = 9.8 x 10² / 6.673 x 10⁻¹¹

                                = 1.47 x 10¹³ kg    

Hence the masses of the two identical spheres are, M = 1.47 x 10¹³ kg    

think its the third option

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
