part a\nof the four fundamental forces presently known, the force of gravity is \nview available hint(s)\nhint 1.\ncheck the value of the universal gravitational constant, g.\nthe weakest\nthe same as the others\nalways downward\nthe strongest
Answer
Brief Explanations:
Among the four fundamental forces (gravitational, electromagnetic, strong nuclear, and weak nuclear), the gravitational force has an extremely small coupling constant. The universal gravitational constant G is very small ($G = 6.67\times 10^{- 11}\ N\cdot m^{2}/kg^{2}$), making gravity the weakest of the fundamental forces.
Answer:
A. the weakest
