The electric field was defined as E⃗ =F⃗ onq/qE→=F→onq/q, and we used this to find the electric field of a point charge. Using analogous reasoning, what is the gravitational field g⃗ g→ of a point mass?Write your answer using the unit vector r^r^, but be careful with signs; the gravitational force between two "like masses" is attractive, not repulsive.

How does a circuit breaker protect a refrigerator? a. when the current is too high, a metal strip in the fuse melts and opens the circuit. b. when the resistance is too high , a re-settable which opens a circuit c. when the current is too high , a re-settable switch opens the circuit d. when the resistance is too high a metal strip in the fuse melts and opens the circuit
