A flower--a large conducting mass on top of a narrow stem--and the ground together act like a capacitor. The flower is one electrode, the earth is the other. A typical value of the capacitance is 0.80 pF . The electric field of the earth induces a charge on the flower and an opposite charge on the ground below. Part A If a flower carries a charge of magnitude 40 pC , what is the approximate potential difference between the flower and the ground below?
