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.

The gravitational force can only be attractive and it acts between bodies with a mass. Coulomb force or electric force can be repulsive or attractive, depending on the charge. If the charge are the same, meaning both are positive or both are negative, the electric force is repulsive. If both charges are different, meaning, one is positive and the other is negative, the electric force is attractive. Also, electric force doesn't act between bodies that are electrically neutral. 

Correct statements are: 2. The gravitational force can be attractive
                                       3. The electrical force can be repulsive
                                       4. The electrical force can be attractive
                                       5. Any two objects experience a gravitational force                                                between them

Statements 1. and 6. are incorrect.
