Atomic physicists usually ignore the effect of gravity within an atom. to see why, we may calculate and compare the magnitude of the ratio of the electrical force and gravitational force fe fg between an electron and a proton separated by a distance of 3 m. what is the magnitude of the electrical force? the coulomb constant is 8.98755 × 109 n · m 2 /c 2 , the gravitational constant is 6.67259 × 10−11 m3 /kg · s 2 , the mass of a proton is 1.67262 × 10−27 kg, the mass of an electron is 9.10939 × 10−31 kg, and the elemental charge is 1.602 × 10−19 c. answer in units of n. what is the ratio of the magnitude of the electrical force to the magnitude of the gravitational force? answer in units of n.

Explanation:

The gravitational force between the proton and the electron is given by

where

G is the gravitational constant

is the proton mass

is the electron mass

r = 3 m is the distance between the proton and the electron

Substituting numbers into the equation,

The electrical force between the proton and the electron is given by

where

k is the Coulomb constant

is the elementary charge (charge of the proton and of the electron)

r = 3 m is the distance between the proton and the electron

Substituting numbers into the equation,

So, the ratio of the electrical force to the gravitational force is

So, we see that the electrical force is much larger than the gravitational force.

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
