Really? It just feels wrong I guess

anonymous · Answer

Two point charges of +30.0 µC and -9.00 µC are 20.0 cm apart.  What is the magnitude of the electric field midway between these two charges?
	A.	1.89 x 107 N/C
	B.	3.51 x 107 N/C
	C.	-1.89 x 107 N/C
	D.	-3.51 x 107 N/C

I think its B

anonymous · Answer

so, what would be the correct answer ? do you have an idea ?

anonymous · Answer

For this question,  you can use

anonymous · Answer

E=q/r^2 

Be careful that Electric field is a vector quantity.

anonymous · Answer

oh its negative

anonymous · Answer

It was B....
