The gravitational force between two electrons 1.0 m apart is 5.42 x 10^-71. Find the mass of the electron.

Explanation:

Given that,

The gravitational force between two electrons is

The electrons are 1 m apart.

The formula for the gravitational force is given by :

Where

m is the mass of the electrons

So, the mass of the electron is .

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
