The gravitational force of attraction between two spherical bodies, each of mass 1kg placed at 10m apart is:

• A.  \[\text{6}.\text{67}\times \text{1}{{0}^{-\text{13}}}\text{ N}\]        
• B.  \[\text{6}.\text{67}\times \text{1}{{0}^{-11}}\text{ N}\]
• C.  \[\text{6}.\text{67}\times \text{1}{{0}^{-\text{7}}}\text{ N}\]                  
• D.  \[\text{6}.\text{67}\times \text{1}{{0}^{-4}}\text{ N}\]
