Someone please help me, I am having the worst time understanding this problem. Where do I begin?
Atomic physicists ignore the effect of gravity within an atom. To see why, calculate and compare the gravitational and electrical forces between an electron and a proton separated by 10-10m.
Ok, do it
Fe= kqq/d^2
Fg=GMm/d^2
I will be happy to critique your thoughts.

I will be happy to critique your thoughts. You knwo the charge on an electron/proton for the electrical force, and you know the masses for the gravitational force.
what? i know the masses yes not sure about the charge. . . but the fromula i have is f=k g1f2/r^2 so And all these numbers are something to the power of something else how do i work that out?
Im confused ok i have that the mass of a proton is 1.6726231 x 10^-27 and the mas of an electron is 9.1093897 x 10^-31
charge of an electron is 1.602 x 10^-19 what do i do with all of this, is g1 the charge of the proton g2 the charge of the electron? what is d is that 10 m?
You have the charges right. Now use your calculator to solve each. Your text will give you the value of G, and k.
To begin understanding this problem, let's break it down step by step:
1. Understanding the forces involved:
In this problem, we have two forces: gravitational force and electrical force. The gravitational force is the force exerted between two objects with mass, and the electrical force is the force exerted between two objects with electric charge.
2. Identifying the given values:
The problem states that we have an electron and a proton separated by a distance of 10-10m. The electron and proton have specific masses and charges that we can use to calculate the forces.
3. Calculate the gravitational force:
To calculate the gravitational force, we can use Newton's law of universal gravitation, which states that the force between two masses is given by the equation: F_grav = (G * m1 * m2) / r^2.
Here, G is the gravitational constant, m1 and m2 are the masses of the interacting objects, and r is the distance between them.
4. Calculate the electrical force:
To calculate the electrical force, we can use Coulomb's law, which states that the force between two charged objects is given by the equation: F_elec = (k * q1 * q2) / r^2.
Here, k is the electrostatic constant, q1 and q2 are the charges of the interacting objects, and r is the distance between them.
5. Compare the forces:
Once you have calculated both forces, compare their magnitudes to see which force is stronger.
To get started with the calculations, you will need to look up the values for the gravitational constant (G) and the electrostatic constant (k), as well as the masses and charges of the electron and proton.
