How do I figure out the direction? The diagram arrows point towards in both ways?

When an object is placed at the principle focus of a complex lens, then the image is A) larger and inverted B) smaller and inverted C) the same size and inverted D) not formed at all Incorrect. Your answer=C, Correct answer=D MY QUESTION: WHAT ON EARTH IS A COMPLEX LENS? CONVEX OR CONCAVE? thanks

Erm, how do I go about the vector addition? I have lEl= kQ/x^2 for the field of B and lEl=k(-Q)/x^2 for field of A. and shouldn't it be southeast? Why do you say it's southwest?

Bump!

Erm, I still don't see the connection? The + attracts the - charge, and i guess i have to use pythagorean theorem, but how do i calculate which direction it is deflected? I need a explanation, i totally suck at this topic..

BUMP! There is the attachment for the diagram. :)

Two charges are placed at an equal distance x from point P, as shown in the following diagram. Charge A is placed directly west of P and B is placed directly north of P. 1)If A is given a charge of –Q and B is given a charge of +Q, what is the direction of the resulting electric field at...
