A particle with a mass of 2.0×10−5 kg and a charge of +2.0 microC is released in a (parallel plate) uniform horizontal electric field of 13 N/C. If the plates are 5.6 cm on each side, how much charge is on each? (in pC) From what I have so far, the formula E=(4piKQ...

I think you forgot to include the actual question part...

I whole-heartedly agree!

Two charges, -2.0 micro C and -6.0 micro C, are located at (-0.65 m, 0) and (0.65 m, 0), respectively. There is a point on the x-axis between the two charges where the electric field is zero. Find the location of the point where the electric field is zero.
