I'm trying to find the gravitational force of an electron at earth's surface.

I know I say Fg = mass electron * gravity

Gravity in this case is 6.673*10-11 m^2/kg^2 correct, not 8.93 * 10^-30N that we used for force of acceleration, right. I use the universal constant of acceleration, correct-6.673 *10^-11 I'm having a disagreement with my brother who is saying the opposite one I should use. Please help

What is wrong with this?

gravitationalforce= masselectron*GravityField

= masselectron*9.8N/kg

Now if you want to do it the hard way, then

Fg= G*Mearth*Masselectron/radiusearth^2

G=6.673E-11 MassEarth, look it up

I do not understand what you are doing.

We're just learning this and I think I mixed up G=6.673E-11 from another problem and what my brother was telling me to simply do mass of electron * 9.8N/kg.

I was accidentally combining two differnet things and not doing it correctly sorry for not understanding it right away when my brother told me-
Thank you for helping

To find the gravitational force of an electron at Earth's surface, you can use the formula:

Fg = (mass of electron) * (acceleration due to gravity)

The constant you are referring to, 6.673 * 10^(-11) m^3/(kg * s^2), is called the Universal Gravitational Constant (G). It is used to calculate the gravitational force between any two objects in the universe, based on their masses and the distance between them.

However, in this case, since you are specifically looking for the gravitational force of an electron at Earth's surface, you need to use the acceleration due to gravity on Earth, denoted as "g". The value of "g" is approximately 9.8 m/s^2.

Therefore, the correct formula to use is:

Fg = (mass of electron) * (acceleration due to gravity on Earth)

Regarding your brother's suggestion of using the value 8.93 * 10^(-30) N, this seems to be a confusion between the units of force and the constant G. 1 newton (N) is equal to 1 kg * m/s^2, which is the unit of force. The value 8.93 * 10^(-30) N does not correspond to the constant G.

In summary, you should use the acceleration due to gravity on Earth (approximately 9.8 m/s^2) to calculate the gravitational force of an electron at Earth's surface, and not the Universal Gravitational Constant (G).
