- Homework Statement
- Position vector of q is î+j(hat)+2k(hat) and position vector of 4q is 2î+j(hat) +3k(hat). Find the position vector of neutral point.

- Relevant Equations
- Electric field vector due to q+Electric field vector due to 4q=0

This is the general suggested approach given in a textbook.

My question is why can I not directly write it in vector form?

E1 vector + E2 vector =0 should be valid no?

Why are they choosing to write E1 mag + E2 mag=0

Then find a vector form

Then convert the magnitude equation into a vector one?

What I did is:

I know we cannot cancel vectors so this just might be the worst approach but I dont get how we used the first approach just like that....
