How are the gravitational force and the electrostatic force alike and different?
They both act between two bodies without any means of contact. However gravitational force acts on mass while the electric force acts on charge. Gravitational force are only attractive while electric field can be attractive/repulsive. Electric field is much stronger than gravitational field.
What is the difference between gravitational force and electric force in terms of attraction and repulsion select two answers?
Gravitational and Electric Force The gravitational force is always attractive and it is proportional to the masses of the objects and inversely proportional to the distance between them. The electric force is also inversely proportional to the distance between the charges.
How are Coulomb’s law and gravitational force similar to each other how are they different?
You should notice that the formula for Coulomb’s law and the Gravitational Law are very similar in that they both operate by the inverse square and both have constants. They also differ in the gravity is always attractive and charges can attract or repel.
What is one way that the electric force is like the gravitational force they both?
Comparing electric force and gravitational force Like gravitational force, whose magnitude increases with mass, electric force magnitude increases with the magnitude of the charges. Both forces act along the imaginary line joining the objects.
How is gravitational force different from other forces?
Gravity is a real weakling – 1040 times weaker than the electromagnetic force that holds atoms together. Although the other forces act over different ranges, and between very different kinds of particles, they seem to have strengths that are roughly comparable with each other.
Is gravitational force stronger than electrostatic force?
The electrostatic force between two subatomic particles is far greater than the gravitational force between the same two particles.
Why are electrostatic forces stronger than gravitational force?
Electrostatic forces are much stronger than gravitational forces. This is because gravity depends on mass, atoms have tiny masses so t hat the gravitational forces between them is close to zero. Whereas, the electrostatic force related to charges is bigger.
What is difference between gravitational force and Coulomb force?
The gravitational force between two masses is always attractive but Coulomb force between two charges can be attractive or repulsive, depending on the nature of charges. The gravitational force between two point masses is the same whether two masses are at rest or in motion.
Why is gravitational force is the weakest?
The value of the gravitational constant (6.67 x 10-11) is very small. Therefore, the value of the gravitational force also becomes small. This makes the gravitational force the weakest force.
