Question 6 (1 point) The electric potential of a charge is the electric potential energy per unit mass at a given point in an electric field. Question 7 (1 point) Two identical electric charges ql and q2 are separated by a distance r. If ris tripled, what happens to the electric force between them? 0 decreases by a factor of 3 0 decreases by a factor of 9 0 increases by a factor of 9 Question 1 (1 point) A point charge @ produces a potential I at a distance 7. A positive test charge q is moved from / to a distance of 27. Which is true about the difference in potential experienced by the test charge? It is positive if Q is positive. It is negative if Q is positive. It is negative if Q is negative. It is equal to zero.
