Assignment:
A point charge q = -3.5 x 10-10 C is fixed at the origin, as shown below. Where must an electron be placed relative to the point charge so that the electric force acting on the electron is exactly opposite to its own weight? Include a sketch showing the position of the charges (it does not need to be to scale, but it must show correct position). Draw and label the force vectors on both charges. Assume that the horizontal axes are parallel to the earth surface.
Distance between q and electron = _________.
Provide complete and step by step solution for the question and show calculations and use formulas.
