Question

In addition to the Mg nucleus at x = 3 cm, another 3e charge is situated on the y-axis, 3cm away from the origin in the +y direction as shown below:


What is the magnitude of the Electric Field halfway between the Magnesium nucleus and the 3e charge on the y axis in N/C?
Distance between charges is d=sqrt{3²+3²} =4.24 cm
x=d/2 =4.24/2 =2.12 cm =0.0212 m
E=kq₁/x²-kq₂/x² =
=k12e/x²-k3e/x²=k9e/x²=
=9•10⁹•9•1.6•10⁻¹⁹/0.0212²=
=2.9•10⁻⁵ N/C
hai why is marked incorrect did u get green check on this question ?? and thx for support

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?
3.84e-23
