No, because the gravitational constant is much smaller than the electrostatic constant. Answer A: No, because the gravitational constant is much smaller than the electrostatic constant. A No, because the gravitational force is only attractive, and the electrostatic force can also be repulsive. Answer B: No, because the gravitational force is only attractive, and the electrostatic force can also be repulsive. B Yes, because both forces have the same 1/ r2 dependence. Answer C: Yes, because both forces have the same 1/ , r, 2, dependence. C Yes, because the gravitational force always equals the electrostatic force at any given distance.
