The graph above shows the potential V as a function of position x for a non-uniform electric field. At which position is the magnitude of the electric field the greatest.?

A 0.069 μF capacitor is being held at a potential difference of 24 μV.  Part (a)  What is the charge, in coulombs, on one of the plates?                       Part (b)  If you measure the size of each plate to be 41 cm2, how far apart are the plates, in micrometers?                                                                            Part (c)  What is the magnitude of the electric field inside this capacitor, in newtons per coulomb?

The figure below shows the equipotential surfaces of an electric dipole in the xy-plane. The x and y scales are in units of meter. The charge on the left is positive. Each color change represents a a change in the potential of 5 V. Estimate the magnitude and direction of the electric field in units of V/m N/C at x 13.5 m, y = 13.5 m. = 24.5 22.5 20.5 18.5 16.5 14.5 12.5 10.5 8.5 6.5 4.5 2.5 0.5 0.5 2.5 4.5 6.5 8.5 10.5 12.5 14.5 16.5 18.5 20.5 22.5 24.5
