Two objects, A and B, are 10 m apart. Objects C and Dare 20 m apart. The gravitational attraction between objects C and D is greater than the attraction between objects A and B. Explain the reason for the difference in gravitational attraction.

Answerit increases at a steady rate;

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
