Which of the following would decrease the overall force felt between two charges the most? Question 9 options:
A. Doubling the charge on the first object
B. Doubling the charge on the second object
C. Doubling the distance between the charges

If one charge is tripled and the other is cut in half, what happens to electric force?

Question 10 options:
A. It is decreased by 10 times the original force
B. It is increased by 1.5 times the original force
C. It is increased by 10 times the original force
D. It is decreased by 1.5 times the original force

#9 is C.  Increasing the distance will effectively reduce an attraction.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
