1 AnswerPolls & Surveys1 week agoHow is Coulomb’s law similar to Newton’s law of gravitation? How is it different?
a. Both forces vary inversely as the square of the separation distance between the two objects; electrical forces may be either attractive or repulsive, whereas gravitational forces are always attractive.
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.
