How does the strength of electrical force compare to the gravitational force?

Electrostatic forces are similar to gravitational forces in that they both conform to the distance squared law and are proportional to the properties of the two actors in the interaction (in terms of electrical forces, the charges of the two point charges; and in gravitational, the masses of the two bodies). However, though their interactions looks similar the greatest difference is their strengths. The constant of scale for electrostatic forces (Coulomb's constant) is about 9 x 109 in magnitude, whereas the constant of scale for gravitational force (gravitational constant) is about 6.67 x 10-11 in magnitude. Therefore, the electrostatic force scales much faster than gravitational force. Therefore, it is common to see large objects such as the earth exert a tiny force with respect its size, while a small charged Styrofoam ball can push another with relative ease.

∙ 11y agoRegarding their relative strength, this is the example I always like to give:
You've got some bits of tissue on the table. You run a rubber comb through your
hair and pass it over the bits of tissue. They jump up off the table to the comb.
The gravitational force of the whole Earth is pulling them down, and the electrostatic
force of a charged pocket comb is pulling them up. And the comb wins.
Compared to the gravitational force between a pair of 1-kilogram masses, the
electric force between a pair of 1-coulomb charges the same distance apart is
about 10,000,000,000,000,000,000,000,000,000,000,000,000,000 times as strong.
As my freshman Physics prof used to tell us: If every kilogram of mass in the Earth
and your body were coulombs of charge instead, then when you slipped on the ice,
you'd fall down, just as you do now, but you'd fall 1040 harder.

Which force do you compare the electrostatic force to?
Gravitational force.
What affect does mass have on strength of a gravitational force?
The larger the mass, the stronger the gravitational force.
Compare and contrast the electric force with the gravitational force?
gravitation only attracts, while electrical forces attract when the electrical charges are opposite and repel if the charges are similar. Thus, gravitation is considered a monopole force, while electrostatics is a dipole force. However, the concept of dark energy, which seem
How does mass affect the gravitational force of an object?
The strength of the gravitational force of attraction between two objects is proportional to both masses.
What is the difference between electeical forces and gravitational forces?
-- Electrical force only cares about the charge on two objects, and ignores their mass. Gravitational force only cares about the mass of two objects, and ignores their charge. -- Electrical force can be attractive or repulsive. Gravitational force can only be attractive.
Which force do you compare the electrostatic force to?
Gravitational force.
What affect does mass have on the strength of a gravitational force?
The larger the mass, the stronger the gravitational force.
What affect does mass have on strength of a gravitational force?
The larger the mass, the stronger the gravitational force.
How does the planets mass affect the strength of gravitational force?
The greater the mass, the greater the gravitational force.
Difference between electric forces and gravitational forces is that electrical forces include?
In case of electric force there are both repulsive and attractive. But in case of gravitational force, only attractive force. Electrical force between electric charges. Gravitational force between masses. In electric force we use a constant known as permittivity of the medium. But in gravitational force a universal constant known as Gravitational constant is used. Electrical force is very much greater than gravitational force.
How does gravitational force acting on the planet compare to the gravitational force acting on the moon due to the planet?

What are two forces that you can compare and contrast?
gravitational force & electrostatic force.
What directions can electrical force and gravitational force act?
Electrical can either attract or repel - gravity can only attract.

How are gravitational field and an electrical field similar?
The electrical field force acts between two charges, in the same way that the gravitational field force acts between two masses.
