Question

Which statements correctly compare the gravitational force with the electrical force? Check all that apply.

The gravitational force can be repulsive.
The gravitational force can be attractive.
The electrical force can be repulsive.
The electrical force can be attractive.
Any two objects experience a gravitational force between them.
Any two objects experience an electrical force between them.

Answer 1

Correct statements:
- The gravitational force can be attractive. (True — gravity between masses is always attractive in the usual sense.)
- The electrical force can be repulsive. (True — like charges repel.)
- The electrical force can be attractive. (True — opposite charges attract.)
- Any two objects experience a gravitational force between them. (True — any two masses exert gravitational attraction on each other.)

Incorrect statements:
- The gravitational force can be repulsive. (False in the usual Newtonian sense.)
- Any two objects experience an electrical force between them. (False — two electrically neutral objects have no net Coulomb force; they can have small induced/van der Waals forces but no net Coulomb force unless there is net charge or charge separation.)
