A spark plug in an automobile enfine consists of two metal conductors that are separated by a distance of 0.5 cm. When an electric spark jumps between them, the magnitude of the electric field is 4.0 x 10^7 V/m. What is the magnitude of the potential difference V Between the conductors

Q5/ An electric field of 8.5 x 105 V/m is desired between two parallel plates each of (7 cm x 8 cm) and separated by 3.5 mm of air. What charge must be on each plate? What is the value of energy stored in the capacitor? A dielectric insulator has been inserted between the two plates.What is the value of K for this insulator in order to double the charge on the plates?
