Im not sure if I have the right equations here. I am totally clueless on this problem

I don't think I am following you. Use which equation? I did x(99)=(x+21)(127) and got -95.25 I used C=QV

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. What is the capacitance of the capacitor?Homework Equations There is Q=cV, or C=Q/v. But there are 2 unknowns and no number for the...

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? Homework Equations Im not sure what form of the magnitude equation to use for...
