[QUOTE="TSny, post: 6865894, member: 229090"] Please type in your posts rather than post your discussion as images. Otherwise, it isn't easy to quote specific parts of your post. Posting images of diagrams is fine. If the net electric field is not zero at the instant t = 0 when the two particles "cross", then I don't understand the setup of the problem. You say that E[SUB]net[/SUB] = 0 is not the "given result". If you can state the given result, it might help us interpret the setup. You stated the following: What does it mean when you say "two charges are x"? Your formula for ##\mathbf{E}(\mathbf{r}, t)## must correspond to some configuration of the two charges. Can you post a carefully sketched diagram that shows the location of the two particles at the instant that corresponds to your formula? On the diagram, please indicate the location of the two particles and the location of the field point. Also, please label the quantities ##x##, ##r##, ##\hat {\mathbf{r}}##, and ##\theta##. [/QUOTE]
