In which way is the electric force similar to 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 electric force similar to gravitational force?

Both gravitational and electric field obey inverse square laws (e.g. F(grav)=GMm/r^2 and F(electric)=kq1q2/r^2 where GMm and kq1q2 are constants). They both act between two bodies without any means of contact. However gravitational force acts on mass while the electric force acts on charge.

How is an electric field similar to a gravitational field?

Electric fields are similar to gravitational fields – both involve action-at-a-distance forces. In the case of gravitational fields, the source of the field is a massive object and the action-at-a-distance forces are exerted upon other masses.

Which force is equal to the gravitational force?

Explanation: The normal force on an object at rest on a flat surface is equal to the gravitational force on that object. In equation form, that means . Use Newton’s second law ( ) to solve for the gravitational force, using acceleration due to gravity as your .

Is electric force greater than gravitational force?

The electrostatic force between two subatomic particles is far greater than the gravitational force between the same two particles.

In which way are gravitational force and electrical force the same quizlet?

Gravitational force between any two particles of mass. Electric force between any two particles with charge. Gravitational force is only attractive. Electric force causes unlike charges to attract and like charges to repel.

How are magnetic and electric forces similar?

Similarities between magnetic fields and electric fields: … Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract. Electric field points in the direction of the force experienced by a positive charge …

Why is electric force stronger than gravitational?

The gravitational force is directly proportional to the mass of both objects. The electrostatic force is directly proportional to the charge of the objects. … Therefore, gravitational forces dominates.

Are gravitational forces equal?

The force is proportional to the product of the two masses and inversely proportional to the square of the distance between the point masses’. … The gravitational force on Earth is equal to the force the Earth exerts on you. At rest, on or near the surface of the Earth, the gravitational force equals your weight.

Do all objects have the same gravitational force?

On earth, all objects (whether an elephant or a feather) have the same force of gravity. The elephant weighs more than the feather, yet they each have the same mass.
