7 Electric fields and gravitational fields can be depicted using similar types of diagrams. Which statement correctly describes how the two fields are depicted using standard conventions?
A. Electric fields can be shown in two directions, toward a positive charge and away from a negative charge,
while gravitational fields are always shown in one direction, toward the mass.
B. Electric fields can be shown in two directions, away from a positive charge and toward a negative charge,
while gravitational fields are always shown in one direction, toward the mass.
C. Electric fields are always shown in one direction toward the positive charge, while gravitational fields are
always shown in one direction, toward the mass.
D. Electric fields are always shown in one direction, toward the negative charge, while gravitational fields are
always shown in one direction, toward the mass.
