The peak instantaneous current in a certain lightning stroke is 21,700 A vertically upward. The current is approximately constant at this value for 1.2 x 10^-4s.

(a) Find the charge transferred to the ground during this time interval.

(b) The current at one point in the lightning bolt is produced by electrons moving at a speed of 1.1 x 10⁷ m/s through a circular cross section of radius 0.90 cm. What is the number of electrons per m³ in the discharge?

(c) Assuming this same electron density throughout, what is the total charge contained in a 1.0 km long lightning bolt that has an average cross-sectional area of 1.0 cm²?
