Question

If the 3e  charge is at the origin and the Magnesium nucleus is 3cm  from the origin in the +x  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 =

Elena · Answer

E=kq₁/x²=kq₂/(3-x)² 3e/x²=12e/(3-x)² 9-6x+x²=4x² 3x²+6x-9=0 x²+2x-3=0 x=1 cm

What is the magnitude of the net electrostatic force a Boron nucleus would experience at the point halfway between the Magnesium nucleus and the 3e charge on the y axis in N?

Its not ok. If x=1cm, the e- have a net force to the rigth x=-3cm
