7. Compare and contrast electric force and gravitational force.

8. Describe the conditions under which electric force can either be attractive or repulsive.

Answer :

Answer:

• Gravitation only attracts, while electrical forces attract when the  

       electrical charges are  opposite and repel if the charges are similar.  

      Gravitation is considered a monopole force,  while electrostatics is a

      dipole force.

Explanation:

• The strength of both forces depends on the distance.  

• Both gravitation forces and electric forces obey the inverse square law of distance.

• Both gravitation forces and electric forces can operate even in vacuum.

• Both gravitation forces and electric conservative forces

• Electric force is created by the attraction or repulsion of two charged bodies.

• Gravitational force is created by two bodies being attracted to each other due each body  

       being caught in each other's gravitational field.
