Item 25 The electric field was defined as E - Fon a/g, and we used this to find the electric field of a point charge. Using analogous reasoning, what is the gravitational field g of a point mass? Write your answer using the unit vector , but be careful with signs; the gravitational force between two "like masses" is attractive, not repulsive Newton's law of gravity and Coulomb's law are botlh inverse-square laws. Consequently, there should be a "Gauss's law...
