draw the electric field around these charges. Mark where the field strength is at its strongest and determin how big it is.
@Michele_Laino is it just like this|dw:1427987818137:dw|
the question is not where it is the strongest, it is where it is the smallest
but I dont know how to determin how big it is?
are the charges like-point?
did you see my attachment?
thats the only thing I get
yes!
ok! I consider your charge like-point. So we have to keep in mind that the electric field caused by each charge, is given by the subsequent formula: \[{\mathbf{E}} = \frac{q}{r}{\mathbf{\hat r}}\]
oops.. \[{\mathbf{E}} = \frac{q}{{{r^2}}}{\mathbf{\hat r}}\]
where q is the value of the charge, r is the distance from the charge, and \[{\mathbf{\hat r}}\] is the unit vector whose direction is the same as the direction ov the position vector \[{\mathbf{r}}\]
