Lesson 3: Coulomb's law and electric force

Comparing electric force and gravitational force

Two protons are placed near each other. One proton exerts both an electric force F, start subscript, E, end subscript and a gravitational force F, start subscript, G, end subscript on the other proton.

How does the magnitude and direction of F, start subscript, E, end subscript compare to F, start subscript, G, end subscript ?

(Choice A)
vertical bar, F, start subscript, E, end subscript, vertical bar, is greater than, vertical bar, F, start subscript, G, end subscript, vertical bar, and opposite direction
(Choice B)
vertical bar, F, start subscript, E, end subscript, vertical bar, is greater than, vertical bar, F, start subscript, G, end subscript, vertical bar, and same direction
(Choice C)
vertical bar, F, start subscript, E, end subscript, vertical bar, is less than, vertical bar, F, start subscript, G, end subscript, vertical bar, and opposite direction
(Choice D)
vertical bar, F, start subscript, E, end subscript, vertical bar, is less than, vertical bar, F, start subscript, G, end subscript, vertical bar, and same direction
