Which of the following statements regarding gravitational, electric and magnetic fields is false?
In physics, fields are models used to explain gravitational, electric and magnetic forces.
Gravitational, electric and magnetic fields are vector fields which have both magnitude and direction.
Gravitational, electric and magnetic fields surrounding the source of the field spread out radially and their magnitudes are inversely proportional to the distance from the source.
A vector field created by multiple sources can be calculated using vector addition by combining the fields created by the individual sources.
