Question
Coulomb's law is F=kq1q2/r2 where k=8.988x10^9 Nm2/C2=a constant of nature. This Coulomb's law resembles the law of universal law of gravitation except that the k constant is much stronger. It is one of natures patterns of symmetry. Compare feebleness of gravity G=6.672x10^-11 Nm2/kg2. What is the difference in orders of magnitude between the two constants?

Ans: Both of the two laws do have some resembalance.Because both of then is a inverse square law i.e the magnitude of force will be directly proportional to the inverse square of the distance.And both of the two potential gives bound motions, as for example for Planetory motion under the action of gravity and the motion of electron inside the atom under the Coulomb attraction field of the electrostatics.
Gravity dominates the large scale structure of the universe, but only so to speak by default. Matter arranges itself to cancel electromagnetism, and the strong and weak forces are intrinsically short-ranged. At a more fundamental level , gravity is extravagantly feeble.acting between protons, gravitational attraction is about 10-36 times weaker than electrical repulsion.And this hing quantitatively says Gravity is extravagantly feeble.
Now k=8.988x10^9 and G=6.672x10^-11 so k/G=1.34x 10^20 so they differ by 10^20 order of magnitude.
