Question

Help number five physics In the three diagrams, the circles represent small balls that carry electric charges. In Diagram A, ball 1 carries a negative charge, and ball 2 is repelled byball 1. In Diagram B, we see that ball 2 now repels ball 3. In Diagram C, we see that ball 3 now attracts ball 4. Based on these diagrams, what is theelectric charge on ball 4?

Answer 1

Question 5

Given:

Ball 1 has negative charge.

Ball 2 is repelled by ball 1.

Ball 2 repels ball 3.

Ball 3 attracts ball 4.

To find the electric charge on ball 4.

Explanation:

Like charges repel each other.

Example - Positive and positive charge repel each other.

Also, negative and negative charge repel each other.

Unlike charges attract each other.

Positive and negative charge attract each other.

In the first diagram, ball 1 and ball 2 repel each other which means ball 2 has negative charge.

In the second diagram, ball 2 and ball 3 repel each other which means ball 3 has negative charge.

Now, in the diagram 3, ball 3 and ball 4 attract each other which means ball 4 has positive charge.

Thus, ball 4 has positive charge.
