What is the magnitude of the electric field at a point midway between a -5.9 uC and a +8.2 uC charge 8.8 cm apart? Assume no other charges are nearby. Express your answer using two significant figures: E= (what value) in (what units)? What is the direction of the electric field? Toward the positive charge Toward the negative charge P.S. I know nothing about this but I have a good idea are some quick google help. I feel like I understand the concept but I want to verify the work before I'm able to help a friend with this problem. It would be helpful if you can list all the steps- I can reverse engineer with no issues.

A proton is placed directly in the middle of a parallel plate system, as shown below. The parallel plates have a potential difference of 2800 V and a separation of 32 cm. a) Will the proton travel to the left or to the right? b) If the proton starts at rest, what will its velocity be when it reaches the plate that it is travelling towards? c) Suppose instead that instead of starting at rest, the proton is travelling in the upwards direction with a constant velocity. If you wanted to balance the proton so that it doesn’t head towards either of the parallel plates, you could use a magnetic field. Would the magnetic field need to be pointed into the page or out of the page?
