4.8 Difference between Electric and Gravitational Fields

Question 1

Similarity In terms of strength ?

Answer 1

It is the force per thing that causes interaction (charge or mass)

Question 2

Similarities between laws?

Answer 2

Coulomb’s Law and Newton’s Law of Universal Gravitation are both inverse square laws.

Question 3

Similarities in the field lines direction?

Answer 3

Towards point mass/charge for negative charge and all objects of mass

Question 4

Similarities in the potential energy?

Answer 4

Zero at infinity and is per unit of the thing creating the interaction (mass or charge)

Question 5

Differences in terms of type of forces?

Answer 5

Gravitational are always attractive

Electrostatic can be repulsive or attractive

Question 6

Differences between objects affected?

Answer 6

Gravitational fields effect objects of mass

Electric fields effect objects of charge

Question 7

Differences in terms of shielding?

Answer 7

Objects can shield from electric fields

Objects cannot shield from gravitational fields

Question 8

Differences in sizes due to medium?

Answer 8

Gravitational field strength doesn’t change in different mediums.
Electric field strength depends on medium it is created in
