In summary, an electron with a mass of 9.110×10-31kg and charge of -1.602×10-19C is released at rest above the Earth's surface where g = 9.81 m/s2. The second electron directly below it exerts an electrostatic force that cancels out the gravitational force. The distance between the two can be found by equating the force of gravity to the electric force, using the formulas F=ma and F=kq1q2/r^2, and solving for the distance. This can be done by plugging in the given values and solving for r using a calculator.

An electron (mass of 9.110×10-31kg and charge of -1.602×10-19C) is released at rest above the surface of the Earth (where g = 9.81 m/s2). A second electron directly below it exerts an electrostatic force on the first electron that exactly cancels the gravitational force. What is the distance between the two?

The Attempt at a Solution


I honestly don't know at all how to solve this. If someone could explain to me how and maybe show me the initial steps, that would be great!

We aren't supposed to help before you make an attempt.
But I can give you a little hint. Just write the obvious:
force of gravity = electric force
Then look for the formula for each side of the equation and write the next step in formulas. Solve for the quantity you want to find. Put in the numbers and run it through your calculator.
