b. Both forces are proportional to the same constant; electrical forces are only present
on earth, whereas gravitational forces exist everywhere.
c. Both forces proportional to the same constant; electrical forces may be either attractive or repulsive, whereas gravitational forces are always attractive.
d. Both forces are proportional to the product of the masses of the two objects; electrical forces are only present on earth, whereas gravitational forces exist everywhere.
e. Both forces are proportional to the product of the mass of the two objects; electrical
forces may be either attractive or repulsive, whereas gravitational forces are always attractive.
f. Both forces vary inversely as the square of the separation distance between the two
objects; electrical forces are only present on earth, whereas gravitational forces can exist everywhere.
