a)If a Magnesium nucleus is fixed a distance away from a charge, what is the magnitude of the electrostatic force it experiences in Newtons (yes, it is a small force in Newtons)?

b)If the charge is at the origin and the Magnesium nucleus is from the origin in the direction, at what position (in centimeters) along the x-axis should an electron be placed so that it (the electron) experiences no net force? x

1 answer

a. Pure Coulombs law, use the equation

b. Depends on the value of the charge, is it positive or negative?
