can you check this :

That is correct

unlike charges

I like to study more

B because like sign -ve -ve / +ve +ve will repel while -ve +ve will attarct

it’s A

To check whether you chose the correct answer, let's go through the concept together.

The repelling force between two charged objects occurs when the charges are of like signs. This is governed by Coulomb's Law, which states that like charges repel each other while unlike charges attract each other.

So, when two charged objects have the same type of charge (positive or negative), they will experience a repelling force.

Based on this information, your answer of option B - "like signs" - is correct.
