Find the electric field midway between a -3.0nC charge and a -5.0 nC charge that are separated by 0.60 m.
The Attempt at a Solution
net ε = ε1 + 2
I drew my -3.0 charge on the left and my -5.0 charge on the right
midway in between is 0.3 m
they are both negative charges, so the fields lines are towards each charge (away from the centre) and the -5.0 charge has more lines, because it has the bigger charge
so I solved for ε 1 and got -300 N/C
I solved for ε 2 and got -500 N/C
I think that ε 1 should be subtracted from ε 2 so the result is
The field overall, I think should point toward the larger negative charge
it should point toward the -5.0 nC charge, in my drawing, to the RIGHT.
is that correct?
