In which case would there be an electrostatic force between two objects?

two positively charged objects****

two neutral objects

a positively charged object and a neutral object

a negatively charged object and a neutral object

correct

A negative charged object and a neutral charged object

The case in which there would be an electrostatic force between two objects is when they have opposite static charges or when one object is charged and the other is neutral. So, the options that satisfy this condition are:

- A positively charged object and a neutral object
- A negatively charged object and a neutral object

In both cases, there would be an attractive force between the charged object and the neutral object due to the difference in their electric charges.
