Question
Use the table of observations about the electric force between charged objects to answer the question.
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?
A repulsive, strong
repulsive, strong
B attractive, strong
attractive, strong
C repulsive, weak
repulsive, weak
D attractive, weak
The answer is C - repulsive, weak.
This can be determined by comparing the observations in the table. When both objects have the same charge (+1, +1), the distance between them is greater (4mm) compared to when they have opposite charges (-1, -1) or (-2, +2), where the distance is smaller (2mm).
Additionally, the table indicates that when the charges are the same (+1, +1 or -1, -1), the electric force is stronger. Therefore, based on these observations, we can conclude that the repulsive force between the two objects with +1 C charges will be weaker than the forces observed in the table (medium or strong).
Based on the data in the table, the most likely type and amount of electrical force between the two objects (one with a charge of +1 C and the other with a charge of +1 C) is:
A repulsive, strong
To find the answer to this question, we need to analyze the data in the table and make a conclusion based on that information.
According to the table, we can see that when two objects with the same charge (+1 and +1) are 4 mm apart, the amount of electric force is described as "medium." This indicates that there is a repulsive force between the objects, as they have the same charge and the force is not too strong.
Next, we look at the observation where two objects with opposite charges (-2 and +2) are 4 mm apart, and the electric force is described as "strong." This suggests that there is an attractive force between the charged objects because they have opposite charges.
Based on the information from the table, we can conclude that when two objects with the same charge (+1 and +1) are 10 mm apart, there will most likely be a repulsive force between them. Since the table does not provide information about the strength of this force at a distance of 10 mm, we cannot determine the exact amount (strong or weak) of the force. However, we can rule out options B and D, as they suggest an attractive force, which contradicts the information in the table.
Therefore, the most likely answer is:
C) repulsive, weak
