The potential as a function of distance is shown in the plot below. Which statement about the electric field is true? Distance (cm) A) The electric field is zero at x=0, its magnitude is at a maximum at x=5 cm, and the field is directed to the left there. B) The electric field is zero at x=5 cm, its magnitude is at a maximum at x=0, and the field is directed to the right there. C) The electric field is zero at x=0, its magnitude is at a maximum at x=15 cm, and the field is directed to the left there. D) The electric field is zero at x=10 cm, its magnitude is at a maximum at x=5 cm, and the field is directed to the right there. E) The electric field is zero at x=10 cm, its magnitude is at a maximum at x=0 cm, and the field is directed to the left there. Potential

A parallel-plate capacitor filled with air has plates of area 6.5×10−3 m2 and a separation of 0.32 mm.  a) Find the magnitude of the charge on each plate when the capacitor is connected to a 11-V battery. (Q = ? nC) b) Why does answer A decrease if the seperation between the plates increases? c) Calculate the magnitude of the charge on the plates if the separation is 0.90 mm. (Q = ? nC)
