Electric force is similar to gravitational force in what way?
  1. Electric force decreases in strength as the distance between the charges increases.
  2. Electric force is similar in strength to gravitational force.
  3. Electric force is both attractive and repulsive.
  4. Electric force is proportional to the mass of the object.
Explanation
Answer: A - Electric force is similar to gravitational force in that electric force decreases in strength as the distance between the charges increases. Both electric and gravitational forces are inversely proportional to the square of the distance of separation. Gravitational forces are always attractive. Electric force is significantly stronger than gravitational force and is not proportional to the mass of an object.
