A charge of - 4.0 µC is located at the origin and a charge of - 5.0 µC is located along the y-axis at y = 2.0 m. At what point along the y-axis is the electric field zero?

Respuesta :

I got y = 0.94427191  and y = -16.944272. Not sure if right tho.

I did  [tex]{k q_1 \over y^2} &= {k q_2 \over (2-y)^2}[/tex], put the known in and solved it.
