Answer:
F=3.15 N pointing south
Explanation:
For the magnitude:
[tex]E =\frac{F}{q}
F = qE = 6*10x^{-6} *5.25*10^{5}[/tex]
[tex]F=3.15 N[/tex]
For the direction:
In the equation F=qE, both F and E are vectors while q is the module of the charge, this means that the direction of the electric field is the one that gives the direction of the force, in this case both point south
