Homework Statement
A C_1 = 2.40 \mu(micro) F capacitor is charged to 861 V and a C_2 = 6.40 \mu(micro) F capacitor is charged to 662 V. These capacitors are then disconnected from their batteries. Next the positive plates are connected to each other and the negative plates are connected to...
Capacitance (Please Help!)
Homework Statement
The charge on a capacitor increases by 21 \mu(micro) C when the voltage across it increases from 99 V to 127 V.

that is the figure they give with the problem. You can see what d is with this. You are probably correct about the meters its been a while since I have worked with SI prefixes.
for q1 the equation I would use is E1=(8.99e9)(3e/(.0067m)^2).
Do I have this setup correctly? I am not quite sure what to do with the e's will an e remain in the answer?
Homework Statement
four particles are fixed in place and have charges q1 = q2 = 3e, q3 = 7e, and q4 = -28e. Distance d = 6.7 µm. What is the magnitude of the net electric field at point P due to the particles?
