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