Question

the diagram shows two charged objects, a and b
based on the field lines, what are the charges of the
objects?
a: positive
b: negative
a: negative
b: positive
a: negative
b: negative
a: positive
b: positive

Explanation:

To determine the charges of objects A and B, we use the rule for electric field lines: electric field lines start from positive charges and end at negative charges.

• For object A: The field lines are originating from A (they are moving away from A), which means A is a positive charge.
• For object B: The field lines are converging towards B (they are moving into B), which means B is a negative charge.

Among the given options, the one that matches this conclusion is "A: positive, B: negative".

Answer:

A: positive
B: negative
