Charge of Object 1 (C) Charge of Object 2 (C) Distance (mm) Amount of Electric Force +1 +1 4 medium –1 –1 2 strong –2 +2 4 strong An object with a charge of +1 C is 10 mm from an object with a charge of +1 C. Based on the data in the table, which type and amount of electrical force will there most likely be between the two objects? (1 point) Responses repulsive, strong repulsive, strong repulsive, weak repulsive, weak attractive, weak attractive, weak attractive, strongg

Answer 1

To determine the type and amount of electrical force between two objects each with a charge of +1 C at a distance of 10 mm, we can refer to the observations provided in the question.

• The table shows that two positive charges (+1 and +1) at a distance of 4 mm exhibit a "medium" electric force.

Since the forces between like charges (both positive in this case) are always repulsive, we can conclude that the force between the two +1 C charges will also be repulsive.

Now, while the exact strength of the force isn't directly given for a distance of 10 mm, we can make an inference based on the pattern observed:

• As distance increases, the force generally decreases; since the force is "medium" at 4 mm, we can expect it to be weaker at 10 mm.

Therefore, the most likely type and amount of electrical force between the two +1 C objects at 10 mm is:

repulsive, weak.
