Question: A charge of +5 C is located at the origin, and a charge of -20 C is located at x = 2 m, i.e., 2 m away from the origin on the x-axis.
Part A: Ignoring infinity, where along the x-axis in units of meters is the Coulomb force equal to zero?
I want help to find where along the x-axis in units of meters is the Coulomb force equal to zero.
